NA6914 Double Row Needle Roller Bearing Retained Needle Design 70x100x54mm Limited Space Transmission Assembly China Factory Supplier
NA6914 comes with retained needle roller construction and machined inner ring. It fits tight installation space and delivers stable heavy radial performance for compact power transmission units.
Supply：OEM available stock support Equivalent：NTN SA3-60A
SA3-60A is a radial spherical plain bearing designed to accommodate heavy radial loads and angular misalignment. Its spherical sliding contact allows relative movement between the inner and outer rings. It is suitable for applications involving oscillating motion, vibration, and changing load directions. The nominal bore diameter is 60 mm.
The bearing uses long, slender needle rollers to provide a large contact area with the raceways. This helps support high radial loads while maintaining a relatively compact structure. It is suitable for industrial gearboxes, transmission equipment, construction machinery, and other mechanical drive systems. The inner ring provides a hardened raceway surface for shaft applications.
A Useful Addition to Your Product Range
NA6914 belongs to the NA69 series. Related models include NA6912, NA6913, NA6915, and NA6916. These models help distributors cover different shaft diameters and equipment requirements. Offering several sizes from the same series can make it easier to serve customers with replacement and maintenance needs.
Replacement and Technical Matching
For replacement orders, customers should check the 70 mm bore, 100 mm outside diameter, and 54 mm width. Shaft fit, housing tolerance, lubrication, and operating speed should also be considered. The standard NA6914 is an open bearing. Sealed versions and other configurations should be checked separately. We can assist with comparing model numbers and technical drawings before order confirmation.
