ZKLDF Rotary Table Bearings

(High Speed Precision Bearings/ Axial Angular Contact Ball Bearings)

ZKLDF series rotary table bearing includes components of an integral outer ring, two inner rings, two sets of steel balls and brass cage. The contact angle is 60 degree, and the inner part is provided with a mounting hole. It is convenient to install the bearing through the connecting bolt. The two sides of the ZKLDF turntable bearing are provided with sealing covers, which can prevent the external dirt enter in and the lubrication grease go out. This kind bearings can bear radial load, bidirectional axial load and short overturning force due to the bidirectional 60 degree contact ball structure design; the special brass cage design also make it have higher strength and lower friction ratio, which is especially suitable for the situation of ultra-high speed, long-term operation and high requirements for rigidity and accuracy.

Bearing Types: ZKLDF100 , ZKLDF120 , ZKLDF150 , ZKLDF180 , ZKLDF200 , ZKLDF260 , ZKLDF325 , ZKLDF395 , ZKLDF460 , ZKLDF580
