Features
- High speed spindle bearings is suitable for high radial and axial loads in one direction.
- Accuracy grade: high precision P2/P4S/P4/P5.
- High speed: 15° and 25°, special cage and optimized internal design make higher speed.
- High rigidity: mounted in pairs (DB/DT/QBC) with preload to eliminate clearance, resists deformation under cutting forces.
Applications
High speed electric spindles, wood carving machine, engraving machine, CNC router, CNC machine, machine tool spindle
Material of Bearing Components
The high speed spindle bearing is a specially designed angular contact ball bearing consisting of an inner ring. An outer ring, a cage, a set of rolling elements and optional grease and seals. According to the customer's use and working conditions, we will provide the corresponding parts materials to achieve the best performance of the bearing.
- Seals: non-contact rubber seals on both sides
- Balls: G5 steel ball
- Rings: OVAKO Sweden steel
- Cages: phenolic resin or polyamide
- Grease: Lubcon or Klueber

Slope Design
ultra-precision spindle bearings are divided into B-series, HCB-series and HCS-series with distinct inner/outer ring slope (chamfer) structures, which fundamentally determine lubrication compatibility, speed threshold and application scenarios:
B Series (Full Steel Ball Standard Spindle Bearing):Inner ring with slope, outer ring without slope. Standard large ball structure, classic high-rigidity spindle design.
HCB Series (Hybrid Ceramic Ball Standard Speed): Both inner and outer rings with slope. Ceramic ball rolling body, standard high-speed structure.
HCS Series (Hybrid Ceramic Ball Ultra-High Speed): Both inner and outer rings with slope. Optimized small ball + special raceway design, ultra-low friction and extreme speed-oriented structure.
Oil mist lubrication priority: B series -- The outer ring no-slope open structure solves the oil accumulation and overheating problems of double-slope bearings, with the most stable lubrication circulation and the lowest long-term operating temperature.
Conventional high-speed oil-gas lubrication: HCB series -- Balanced speed and rigidity, excellent thermal stability.
Oil mist lubrication priority: B series -- The outer ring no-slope open structure solves the oil accumulation and overheating problems of double-slope bearings, with the most stable lubrication circulation and the lowest long-term operating temperature.
Conventional high-speed oil-gas lubrication: HCB series -- Balanced speed and rigidity, excellent thermal stability.
Ultra-high-speed light-load finishing oil-gas lubrication: HCS series -- Extreme speed performance, ultra-low friction and precision attenuation.
