FAQs

Slewing Bearing FAQs

What types of slewing bearings does CHG manufacture?

CHG manufactures four-point contact ball, double-row ball, crossed roller and three-row roller slewing bearings for standard, large and custom rotary equipment.

How do I choose among the four slewing bearing designs?

Four-point contact ball designs suit compact general combined-load support; double-row ball designs provide enhanced load capacity and smooth rotation; crossed roller designs emphasize rigidity and rotational accuracy; three-row roller designs suit the highest heavy-equipment loads. Final selection requires load and duty review.

Can CHG customize mounting holes, seals and lubrication?

Yes. Mounting-hole patterns, ring dimensions, seals, grease or lubrication provisions, material, heat treatment and corrosion protection can be reviewed from drawings and service conditions.

What loads can a slewing bearing support?

A properly selected slewing bearing can support axial load, radial load and overturning moment simultaneously. Capacity depends on structure, size, mounting and operating conditions.

What gear options are available?

Internal gear, external gear and no-gear slewing bearings are available. Please specify gear position, module, tooth count, accuracy, torque and mating pinion information.

What information is needed for a quotation?

Please send the bearing number or drawing, ID/OD/height, bolt circles, gear data, axial/radial/moment loads, speed, duty, environment, application and quantity.
