⚙️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.

 RMO brand P30-25 full complement bearings

⚙️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 clean2. Use with caution3. appropriate tool4. Hot-loading5. 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.
