Ball Screw Support Bearings

High Axial Load Capacity in Both Directions

Available in double-row, O-arrangement designs (and matched pairs), these bearings accommodate high axial loads in both directions while keeping a compact envelope. The maximized/full ball complement further increases load capacity and system stiffness without enlarging the bearing size. Benefit: simpler, more compact support housings with greater capability.

Factory-Set Preload — Zero Backlash, Ready to Mount Bearings are delivered with factory-set preload (light, medium or heavy) that completely eliminates internal clearance and axial play. No on-site preload adjustment, no shimming, no skilled assembly time — mount them and the axis is rigid and backlash-free from the first run. Benefit: zero backlash, zero extra labor hours.

Sealed Versions & Long-Life Lubrication

Available as open or sealed bearings with contact seals (maximum sealing against cutting fluid and debris) or non-contact seals (minimum torque and temperature rise). Many sealed versions come prepacked with grease for life, with optional relubrication grooves — reducing maintenance and downtime in harsh machining environments. Benefit: longer life, lower running cost, better contamination protection.

Universal Matched Pairs & Flexible Arrangements Designed for universal matching (DB / DF / DT and duplex sets), these bearings can be arranged to suit any loading direction and rigidity requirement — from high-stiffness back-to-back pairs to axially loaded tandem sets — and are interchangeable bearing to bearing without selection. Benefit: flexible design, easy procurement and replacement.

Application Versatility The standard solution for: CNC machine-tool feed axes, precision positioning tables, electric injection molding machines, robotics, semiconductor manufacturing equipment, measuring and handling systems — supporting both the fixed end and floating end of the ball screw.
