Slewing Ring Identification
Identifying slewing rings can sometimes be hampered by part worn serial/part numbers or OEM only references. In order to
help identify your slewing ring, we recommend the following:
1. Provide the machine model on which the bearing fits.
2.Provide a quick drawing giving with the following dimensions noted as accurately as possible.
2.1-Inner ring and outer ring diameters
2.2-Inner and outer flange diameters and heights
2.3-The height of the inner ring, outer ring and total assembled height
2.4The PCD of mounting holes in the inner and outer rings. Also note hole size, through or blind and or taped
2.5-Gear detail including number of teeth, approx tooth pitch, tooth height and depth + profile if possible.
Product: Single-row 4-point contact ball series.
Single-row crossed roller series.
Double-row ball series.
Three-row roller series.
Roller and ball combination series.
Light type profile slewing bearing.
Quenching slewing ring bearingslewing bearing The single-row four point contact ball slewing ring is composed of 2 seat-rings.It features compact in design,and light in weight.The balls contact with the circular race at four points,via which the axial force,radial force and resultant moment may be born simultaneously.
It may be used for slewing conveyers,welding arm and positioner,light,medium duty cranes,excavators and other engineering machines.
Materials of rings and rolling parts
Generally, NTL use carbon-chromium bearing steel GCr15SiMn or GCr15 for rolling parts and surface-haredned steel 50Mn, 42CrMo, 5CrMnMo for the rings.
Material of cages
The cages for NTL slewing bearings include integral cage, segment cage and spacer-type cage. We use 20# steel or ZL102 birmasil for integral and segment cages, PA 1010 resin or ZL102 birmasil or QA110-3-105 albronze for spacer-type cages. In recent years with continuous development of material industry , nylon GRPA55.25 started to be applied for segment cages.
Material of seals
Generally, NTL use NBR or VITON for seals. But there still very few slewing bearings NTL manufactured in early period sealing with felted wool.

Features of Slewing Bearings
Slewing bearing is also called: Slewing ring bearing/ Turntable bearing/ Slewing ring etc. Slewing Ring Bearings can accommodate axial, radial and moment loads acting single or in
combination and in any direction. They are not mounted in a housing or on a shaft, but directly to a seating surface. The inner and outer ring are supplied with mounting holes. Both rings may have integral gears. They are also referred to as slewing rings and tabletop bearings. Slewing ring bearing can perform oscillating (slewing) as well as rotating movements. They may be used without gears or with internal or external gears.

Slewing ring bearing is a new type of slewing product, usually called slewing ring, which is usually composed of worm, slewing ring, other components. Since the core components are slewing bearings, they can simultaneously withstand axial forces, radial forces, and overturning moments. Compared with traditional rotary products, the new rotary drive features easy installation, easy maintenance and a greater degree of installation space.
Slewing bearing are widely used in construction applications including truck cranes, manlifts, turntables, port machinery, modular vehicles, small wind power systems and satellite communications.
