No need for pre-load adjustment at assembly. After press-fitting of bearing, it is only necessary to tighten nuts to the specified torque
Compactness and high performance of wheel axles, no need for parts like apacers, thus minimize axial space requirement
Highly rigid and short axles can be used
No need for grease replenishment at assembly
High productivity: the number of parts is increased with simplified assembly work
Large load rating: the bearing can be simultaneously resistant to axial loads in both the directions and large radial load
Large moment stiffness: this bearing can be designed to have a large contact angle. Due to this large distance between pressure center,
this bearing is fully resistant to moments imposed on the wheel during cornering or other similar motion
Thanks to its special internal design, stiffness is further improved to resistance
DAC series wheel bearing is a double row angular contact ball bearing, incorporating an integral outer ring and two separable inner
rings, which is available either with seals or without seals
Appropriate internal axial clearance: since the bearing is designed to have the appropriate internal axial clearance, no need for

pre-load adjustment (dimensional adjustment for spacers), which is necessary for single row bearing assembly
Greasing an appropriate amount of high-grade grease (excellent for heat 150 deg. C and wear resistant) is prepackaged in the bearing
Superior sealed type bearing is mud-proof, dustproof and leakproof (grease). All without the use of shaft seals
Upgrading reliability: high refining and forged bearing steel can be used for the bearing, thereby extending its service time


The diameter of inner ring is from 20mm to 80 mm
