Factory Supply Ball Bearing - 113 series slewing ring with internal tooth used for high precision machinery – Wanda Detail:
The slewing bearing is a special component that integrates rotation and transmission, reduces structural space and reduces equipment weight. In particular, radar turntables and armored rescue vehicle turntables require high-precision, low-noise, high-impact load, and stable rotation turntable equipment, all of which require dedicated rotation support.
The single-row cross roller swivel ring also consists of two inner and outer rings with a compact structure, high manufacturing precision, low weight and little assembly clearance. The inner ring and the outer ring are connected by rollers, the rollers are arranged in a 1: 1 cross, which can simultaneously absorb axial force, tilting moment and larger radial force.
Also 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.
Our slew bearing 113 series are single-row cross roller slewing bearings with teeth on the inner ring, you can use a pinion with it to bring the slewing ring rotary.The following table is the specification for different models:
