Suma Precision Machinery

SUMA Sprag Type One Way Bearings utilize precision-machined alloy steel sprags to deliver fail-safe unidirectional locking for industrial power transmission. Engineered to handle extreme torque loads (up to 3,000,000Nm ) with <3dB noise levels, these clutches provide zero-backlash reverse blocking in critical applications.

Why Suma Sprag Clutch Bearing Outperform:

Torque Capacity Up to 3,000,000Nm: Withstands heavy-load industrial applications

Zero-Slip Locking: Patented roller-ramp design eliminates reverse play

10,000+ Hours Service Life : Precision-ground GCr15 steel + anti-wear coating

Customization : Modify bore sizes (6-600mm), seals, flange types for unique OEM needs

ISO 9001 & SGS Certified :Automotive-grade quality assurance
