⚙️Product Description:
The P30-25 (also written as P30/25) is a high-capacity single row full complement cylindrical roller bearing engineered without a cage to deliver maximum radial load carrying capability in a compact 30x80x21mm profile. By filling the raceway space with the maximum possible number of precision-ground cylindrical rollers, it achieves an exceptionally high dynamic and static load rating compared to standard caged bearings of identical envelope dimensions. Designed for heavy radial shock loads, low-to-medium rotational speeds, and space-constrained oscillatory pivot joints, this cageless unit excels under extreme pressure. We supply these full complement bearings under our proprietary RMO brand while supporting global multi-brand OEM direct sourcing for hydraulic machinery builders, crane sheave manufacturers, and heavy gearbox repair specialists worldwide.

⚙️Product Features:
- Maximized Full Complement Roller Load Capacity: Cageless design maximizes the number of load-bearing rollers, offering maximum radial capacity to withstand massive impact forces.
- Compact Heavy 300-Series Section (30x80x21mm): 30mm bore and 80mm outer envelope provide structural rigidity and resistance to racial deformation under peak peak loading.
- High-Purity Hardened GCr15 Steel: Precision-molybdenum/chrome alloy bearing steel rings and crowned rollers prevent stress concentration along roller edges.
- Superior Shock & Oscillation Resistance: Ideal for heavy radial shock loads, intermittent duty cycles, and slow-speed heavy pivoting where traditional cages risk fracturing.
⚙️Product Application:
Engineered for heavy structural load density, cage-free shock resistance, and compact radial envelopes, the P30-25 / P30/25 full complement cylindrical roller bearing is widely specified in:
- Hydraulic machinery & drives: hydraulic motor reduction planetary gears, high-pressure pump shafts, and hydraulic winch drums.
- Lifting & material handling: crane sheave pulleys, hoist rope drums, conveyor guide sprockets, and elevator tensioners.
- Construction & mining equipment: excavator boom joint pivots, compaction roller vibrator shafts, and crusher drive linkages.
- Heavy industrial gearboxes: steel mill drive quills, heavy reducer input shafts, and marine winch drive trains.
⚙️Precautions:
| 1. Keep clean | 2. Use with caution | 3. appropriate tool | 4. Hot-loading | 5. Be careful of rust |
| Dust will have a bad effect on the bearing, so keep the surrounding clean. | Strong impact during use can easily cause scratches and indentations. | Avoid replacing existing tools, and use appropriate tools. | Bearings are precision parts, so hot installation is recommended. | Sweat on your hands during operation will cause rust, so it is best to wear gloves. |
