description

• Ball screw support bearings are ideally suited for the combined radial and axial loading to support the ball screw. The bearings have a high contact angle for precise positioning of the ball screw, maximum axial rigidity and exact control of lateral eccentricity.

applications

• Machine tool applications

features

• Super long life: EP-steel provides operating life three times longer than that of conventional bearing materials
• An increased number of balls and a 60º contact angle mean higher rigidity
• Higher precision rotation is achieved with low driving power because starting torque is lower than that of tapered or cylindrical roller bearings
• Easy preload adjustment: bearing preload is adjusted to the optimum value at manufacture
• Universal bearings (symbol SU) will give specified preload in DB or DF mounting, and when mounted in tandem, will share load equally
• Simple design of surrounding parts
• Since NSK ball screw support bearings will support axial and radial loads, design of housing and shaft is simpler than that which is necessary for the combined use of thrust and radial bearings
• The bearings are easy to handle owing to incorporation of nonseparable inner/outer rings
• Bearings prepacked with standard grease are available
• New polyamide cage is utilized to obtain higher precision rotation
• Complies with RoHS restrictions on the use of certain hazardous substances in electrical and electronic equipment
