Four Point Contact Bearings<\/h1><\/div>\n\n\n\n

Four-point contact ball bearings are a type of single-row angular contact ball bearing designed to handle main axial loads in both directions as well as limited radial loads. They are characterized by a unique design where the inner ring is split into two halves, allowing the bearing to contact the balls at four points under radial load.<\/p><\/div>\n\n\n\n

ZMS supplies high quality four point contact ball bearings in China for 15 years. There are famous manufacturers in the world like SKF, FAG, NSK and so on. The quality will be perfect. But if you need high quality from China with better price and need custom made for you. Please get in touch with us.<\/p><\/div>\n\n\n\n

Main bearing series:
QJ2 series
QJ3 series
QJ10 series
We can also supply four point contact ball bearings with locating slots.<\/p><\/div>\n<\/div>\n<\/div><\/div>\n\n\n\n

Features<\/strong><\/strong><\/h4><\/div><\/div><\/div>\n<\/div>\n\n\n\n
\n

Design<\/strong>: Consists of a solid outer ring, a split inner ring, and a ball-and-cage assembly. The raceways are designed with a high contact angle (typically 35\u00b0), enabling the bearing to support axial loads in both directions.

Space-Saving<\/strong>: Requires less axial space than double-row angular contact bearings, effectively acting as two single-row angular contact bearings in one compact unit.

Cage Materials<\/strong>: Typically uses brass or polyamide cages, with brass offering durability for high-speed or high-temperature applications and polyamide providing lightweight and low-noise operation.

High load capacity<\/strong>: A large number of balls are incorporated, giving the bearing its high load carrying capacity.

High-Speed Capability<\/strong>: Suitable for high-speed applications, especially under pure axial loads, due to optimized raceway geometry and cage design.<\/p><\/div><\/div><\/div>\n<\/div>\n<\/div>\n\n\n\n
