THE INNOB WAY

Split it. Drop it in. Restart in hours.

No crane. No shaft teardown. No multi-day shutdown. Our split bearings clamp around the shaft in place — so you cut downtime from weeks to a single shift.

RELIABILITY

Common Failure Modes & How to Avoid Them

Most bearing failures are predictable — and preventable. Know the symptoms, the root cause, and the fix before downtime finds you. We help you avoid them with split design and correct fitting.

Abrasive Wear

bearing failure mode
Hover: symptom / cause / fix
SYMPTOM · CAUSE · FIX
SYMPTOM
Uniform scoring on raceways & rolling elements; enlarged clearance, reduced size.
CAUSE
Poor lubrication, contaminant ingress (dust, debris), failed seals.
FIX
Improve lubrication, upgrade seals (contact/labyrinth), clean mounting; split design enables online swap.

Spalling / Pitting

bearing failure mode
Hover: symptom / cause / fix
SYMPTOM · CAUSE · FIX
SYMPTOM
Flaking pits on raceways/rollers, unusual noise & vibration.
CAUSE
Sustained overload, lube-film breakdown, poor fit/alignment.
FIX
Correct sizing & load check, maintain oil film, proper mounting & alignment.

Overheating

bearing failure mode
Hover: symptom / cause / fix
SYMPTOM · CAUSE · FIX
SYMPTOM
Abnormal heat, darkened grease, discolored rings/cage (blue/brown).
CAUSE
Insufficient/wrong grease, tight fit, overspeed, poor cooling.
FIX
Right grease & fill, check fit/clearance, improve cooling; cooling housings for heavy duty.

Corrosion

bearing failure mode
Hover: symptom / cause / fix
SYMPTOM · CAUSE · FIX
SYMPTOM
Rust spots, pitting, often off the load zone.
CAUSE
Moisture, failed seals, poor storage protection, aggressive media.
FIX
Better seals, rust-proof coating/SS parts, preservation, special seals in wet duty.

Cage Fracture

bearing failure mode
Hover: symptom / cause / fix
SYMPTOM · CAUSE · FIX
SYMPTOM
Cage cracked/broken, bearing seized.
CAUSE
Severe vibration, overspeed, cage wear from poor lube, impact.
FIX
Limit speed/vibration, improve lube, reinforced cage.

Split-Face Failure

bearing failure mode
Hover: symptom / cause / fix
SYMPTOM · CAUSE · FIX
SYMPTOM
Oil leakage at the split, halves shift, poor face mating.
CAUSE
Uneven bolt torque, wrong tightening sequence, misaligned faces.
FIX
Cross-tighten to spec torque in steps (8.8-grade, lightly lubed: M10 45–55, M12 80–95, M16 160–200, M20 300–380 N·m); verify face mating & cleanliness before fit.
THE SPLIT ADVANTAGE

Why Buyers Are Switching to Split

The real cost of a bearing isn't the price — it's the hours your line is stopped. Do the math: one avoided shutdown pays for several sets of bearings.

Solid (standard) bearing

What you do today
  • Dismantle coupling, gearbox & shaft
  • 8–12 hours of downtime
  • Crane, crew and high safety risk
  • Production loss billed by the hour

INNOB split bearing

What your line experiences
  • Fit around the shaft — no dismantling
  • Under 1 hour to replace
  • Two fitters, minimal tools, safe
  • Line keeps running — save the hours
SOLID vs SPLIT

One Glance: Solid vs Split — and Why Split Wins

A traditional solid bearing is one piece — to change it you must pull the shaft, coupling and gearbox apart. An INNOB split bearing opens along the shaft axis and clamps back around it. No disassembly, no line stop. Not sure if your machine suits a split bearing? Ask us — we'll tell you in minutes.

TRADITIONAL

Solid Bearing

Solid bearing on shaft
Must remove the shaft
  • One-piece ring — no split line
  • Slide off only after the shaft is out
  • 8–12 hours downtime per change
VS
INNOB SPLIT

Split Bearing

Split bearing around shaft
Fits around the shaft
  • Rings split 180° along the axis
  • Clamp around the shaft — no removal
  • Under 1 hour to replace

CASE STUDY

Real Results: How Much They Saved

Split bearings don't just save effort — they save real money on every overhaul.

10h+
Downtime saved per overhaul
≈ $100,000
Avoided loss at $10,000 / downtime hour

Split bearing retrofit on a mining conveyor

The original solid bearing required dismantling the gearbox and couplings — over 12 hours of downtime per change. After switching to INNOB split spherical roller bearing units, the bearing is replaced around the shaft with no disturbance to the drivetrain.

“Same fault used to cost us a whole shift. Now maintenance finishes in under an hour — the line barely notices.”

INDUSTRIES

Built for Hard-to-Stop Equipment

Every industry below runs machines that are expensive to stop. We match the split bearing, housing and seal to the duty — so maintenance fits the machine, not the other way around.

INDUSTRY 01

Mining & Cement

Dust, shock loads, non-stop conveyors

The Challenge

Conveyors, stacker-reclaimers and kilns run 24/7 in abrasive dust. A solid bearing change means dismantling the gearbox — days of lost production.

Our Solution

  • Split spherical roller — heavy shock loads
  • Triple labyrinth seals against dust
  • Replace around the shaft in hours

The Payoff

  • −70% planned downtime
  • No crane, no drivetrain strip
  • Bores 80–450 mm stocked
INDUSTRY 02

Steel & Metals

Heat, cooling beds, continuous casting

The Challenge

Casters and rolling mills run hot and never stop. Standard bearings fail early under heat and misalignment; a stoppage halts a whole line.

Our Solution

  • Water-cooled plummer block housings
  • Self-aligning split spherical roller
  • Fast custom for non-standard shafts

The Payoff

  • Survives high-heat duty
  • Replace without line stop
  • Bores to 1500 mm
INDUSTRY 03

Power & Wind

Generators, fan & turbine shafts

The Challenge

Generator and fan shafts are long and hard to access. A solid bearing change means a full outage; every hour offline costs the utility heavily.

Our Solution

  • Split cylindrical roller, high-speed EX/GR
  • Fit around the shaft, no outage
  • Full dimension & 3D files for approval

The Payoff

  • Maintenance during operation
  • High-speed, low-vibration
  • Drop-in for SN/SD bases
INDUSTRY 04

Marine & Port

Salt spray, quay cranes, propulsion

The Challenge

Propulsion shafts and quay cranes face salt spray and vibration. Corrosion and a seized bearing can ground a vessel or stop a terminal.

Our Solution

  • Stainless & coated options
  • Waterproof sealed plummer blocks
  • Rapid repair, minimal downtime

The Payoff

  • Corrosion-resistant builds
  • Replace in dry-dock windows
  • Global express shipping
INDUSTRY 05

Pulp & Paper

Long dryers, press rolls, moisture

The Challenge

Dryers and press rolls have very long shafts. Removing a solid bearing means stripping the entire roll line — a multi-day job.

Our Solution

  • Split design for long shafts
  • Moisture-resistant seals
  • Keep the roll in place

The Payoff

  • Hours, not days, per change
  • Less rolls removed
  • Stable, repeatable fit
INDUSTRY 06

Rail & Transit

Traction & auxiliary drives

The Challenge

Traction and auxiliary drives demand high reliability and long service life; failures cause delays and safety risks.

Our Solution

  • Split tapered roller, located-end
  • Bi-directional axial control
  • 100% inspected, traceable

The Payoff

  • Long, predictable life
  • Faster track-side service
  • Full quality docs

OUR STORY

One plant, full process control

INNOB was founded in 2008 in Luoyang, Henan — one of China's historic bases of the bearing industry, home to a mature bearing supply chain. We chose to specialize: split bearings only, made in-house from forging and heat treatment to grinding and final inspection.

Specializing let us master the hard part of split designs — the micron-level fit of the split face — and keep lead times short. Distributors get consistent stock; OEMs get flexible, private-label supply; end users get a faster, cheaper way to maintain hard-to-stop machines.

  • Forging → heat treatment → precision grinding → assembly, all under one roof
  • Split-face fit controlled to microns; full material traceability
  • Flexible MOQ, rapid prototyping, sample & trial orders welcome
