SLZ---double-direction angular contact thrust ball bearing is a bearing unit composed of an integral outer ring, a group of sectile inner rings, steel balls, cage assemblies and sealing. It features compact structure, small size and high rotating accuracy, enduring force in two directions and bearing certain axial load while holding very high radial load, and multiple structure styles, broad adaptability and easy installation. It is widely used in combination lathe or the spiral-rod drive in machining center.

Types of Designs:
Angular contact ball, double-channel outer rings and dissectible inner rings combine into one which can bear double-direction load. Lip seal or gap seal can be adopted according to the circumstances.

Product Precision Accuracy:
Dimensional tolerance and geometrical accuracy is based on GB/T307P4.
Matched steel ball precision grade is Ⅲ (ISO GB/T308).

Materials:
Material for needle roller is GCr15 bearing steel, quench-hardening HRC60---65.
Material for inner and outer races is GCr15 bearing steel, quench-hardening HRC61---65.
Material for cages is reinforced nylon.

Special Directions:
Recommended tightening moment should be exerted during mounting so as to ensure its technical property.
Transmission must be carried out through bearing races when fitting.
Limited by plastic cages, grease and sealing material, operating temperature is not allowed to surpass +1200C during continuous work.
