High Performance Thin Slewing Bearing - Single-row cross-roller slewing ring with external gear 111 series – Wanda
High Performance Thin Slewing Bearing - Single-row cross-roller slewing ring with external gear 111 series – Wanda Detail:
The single-row cross-roller slewing ring is also composed of two inner and outer rings, with compact structure, high manufacturing precision, light weight and small assembly clearance. The inner ring and the outer ring are connected by rollers, the rollers are arranged in a 1:1 cross, which can bear axial force, tilting moment and larger radial force at the same time. The structure of the cross roller bearing itself is a line contact, which can also be understood as a surface contact, and the line surface contact of the crossed round roller bearing is front, back and left, ensuring the stability of the entire layout.
It is widely used in lifting and transportation, military products, medical equipment, bucket wheel machines, park amusement machines, filling machines etc, which play a very important role in construction machinery products.
XZWD slewing bearing 111 series are externally toothed single-row cross roller slewing bearings with teeth on the outer ring, which are generally driven by pinions to achieve a transmission effect. Please see the following table for specific parameters:
