Description
Needle roller bearings are roller bearings with cylindrical rollers that are small in diameter. In spite of their low cross section, needle roller bearings have a high load carrying capacity and are therefore extremely suitable for bearing arrangements where radial space is limited.
Radial needle bearings are cylindrical and use rollers parallel to the axis of the shaft. Thrust needle bearings are flat and use a radial pattern of needles.
Full compliment bearings have solid inner and outer rings and rib-guided cylindrical rollers. Since these bearings have the largest possible number of rolling elements, they have extremely high radial load carrying capacity and are suitable for particularly compact designs.
Application
Needle bearings are heavily used in engine components such as rocker arm pivots, pumps, compressors, and transmissions. The drive shaft of a rear-wheel drive vehicle typically has at least 8 needle bearings (4 in each U joint) and often more if it is particularly long, or operates on steep slopes.
Features:
High Quality Steel - Ultra clean steel to extend bearing life by up to 80%.
Advanced Grease Technology - SKF lubricants that can extend grease life and performance.
High Grade Balls - Quiet and smooth operation even at high speed.
Super Finished Raceways - Specially honed to minimise noise and improve lubricant distribution and life.
Contact Angle - Offered in 15, 25, 30 and 40 degree angles.
Cages - Available in a range of Polyamide, steel and brass cage assemblies.
