Rolling mill bearings

Rolling Mill Support Bearing

Materials:  

Rings & Rollers: Special alloy steel (hardness HRC 62-64) or carburized surface treatment (50% higher wear resistance).  

Cage: High-strength brass or steel cage (impact-resistant).  

 Size Range:  

Metric Series: Inner diameter 200–1500 mm,outer diameter 300–2000 mm,width 100–400 mm.  

Accuracy Classes: P6,P5 (P4 available upon request).  

 Sealing & Lubrication:  

Sealing Options: Labyrinth seals (dust-proof) + integrated grease channels.  

Lubrication: Centralized automatic lubrication system (compatible with high-temperature grease).

Description

Design Principles: Four-row cylindrical rollers distribute loads evenly (95% load distribution efficiency). Flanged outer ring simplifies axial fixation. Performance Highlights: Ultra-High Load Capacity: Dynamic radial load ≥5000 kN (refer to model RMSB1200). High-Temperature Resistance: Special heat treatment ensures ≥80% lifespan at 200°C. Easy Maintenance: Split outer ring design allows on-site roller replacement.

Features

Built for Extreme Conditions

Resists shock,vibration,and contamination from mill scale/water.

Extended Service Life

Logarithmic roller profile reduces edge stress by 30%.

Fast Delivery

80% of standard models are in stock.

Working Principle

 Rolling Mill Support Bearing
Load Distribution: Radial loads are shared by four roller rows,transferred to the housing via the flanged outer ring. Axial positioning is achieved through flange side ribs (axial clearance ≤0.1 mm). Lubrication System: Options include high-pressure oil film lubrication (40 Bar) or automatic grease replenishment.

FAQ

RMSB bearings feature multi-row rollers for 3–5x higher load capacity,integrated seals,and dedicated lubrication ports,tailored for rolling mill demands.
Upgrade to RMSB bearings with centralized lubrication and implement vibration monitoring (recommended threshold: ≤4.5 mm/s).
Do you offer bearing remanufacturing services?
Yes,models with corrosion-resistant coatings and IP66 seals are available for wet conditions.
