RHP – Spherical Roller Bearings Catalogue is the comprehensive reference for high‑capacity bearings designed to accommodate heavy radial loads, axial loads in both directions and severe misalignment. The catalogue presents the complete RHP range with internal designs, cage materials and precision classes. It explains the relationships among dynamic load rating, speed capability and bearing life (L10/Lnm), highlighting how lubrication, contamination control and fit selection directly affect service reliability in steel, mining and process industries.
You will find guidance for shaft/housing tolerances (ISO fits), internal clearance groups (C2 to C5) and preload recommendations for different operating regimes. The text provides practical selection workflows to avoid premature failures due to edge stresses, heat generation or lubrication starvation. Application notes cover split plummer block housings, adapter withdrawal sleeves and sealing arrangements (labyrinths, V‑rings and taconite seals) to achieve long maintenance intervals in dusty and wet environments.
Content overview
- Complete size tables and internal designs (symmetrical/asymmetrical rollers).
- Cage options: steel, brass, polyamide; guidance for shock and vibration.
- Clearance classes, fits, mounting with adapter/withdrawal sleeves.
- Sealing solutions for severe contamination (taconite, labyrinth, V‑ring).
- Life rating, speed limits and frictional torque considerations.
How to use
- Define loads, speed, misalignment and environment (dust/water/heat).
- Select bearing series and cage based on duty cycle and shock levels.
- Choose clearance/fits; verify life L10 and limiting speed in tables.
- Design housing/seals; plan lubrication (grease type/relube interval).
Best practices
- Never transmit mounting force through rolling elements; heat inner ring or use sleeves.
- Check alignment of housings; avoid edge loading on races.
- Use condition monitoring (temperature, vibration, ultrasound) to extend life.
- For wet/dusty sites adopt taconite sealing and centralized relubrication.
