SKF cross taper roller bearing
profile
The design of the XR series SKF cross taper roller bearings http://www.alierbearings.com/brand/skf/index500.html can provide high rotation precision and stiffness in smaller Spaces, which can greatly save material cost.
This type of bearing is the two sets of bearing raceway and roller in rectangular cross installed together, adjacent roller in the opposite direction, install a isolation block between roller and roller, the roller is also equipped with support gasket, this makes the roller of two and a half columns in the same space.
The bearing's Angle and taper geometry makes the bearing effective span several times larger than the actual width of the bearing itself.
XR series bearings are suitable for high speed machine tools such as vertical boring and vertical grinding machines.
It is also especially suitable for many devices with limited space and high rotation precision.
Size range
2463.800 mm (4.000 in) to 97,000 in.
2819.400 mm (11.000 in) to 111.000 in
Design features
XR series has two columns taper roller in the 90 ° V hob surface by interval retainer vertical cross arranged, can bear radial load, axial load, etc. All the direction of the load.
The line contact between roller and roller construction provides maximum rotation precision, high stability and greater tilt stiffness.
The adjustable design of preload extends the bearing life and increases the stiffness and provides the minimum pulsation.
Nylon diaphragm has low inertia and low operating torque.
The components are made of surface carburizing steel or electroslag remelting bearing steel, which has good impact resistance.
Application range
With precision machine tool rotary indexing table, vertical and horizontal boring machine, vertical grinding machine, rotary surface grinding machine, large gear hobbing machine, guns and rotary table, large radio and optical telescopes, rotating camera, steering pivot and continuous casting machine, highly restricted pivot microscope platform, pole center axis, bogie, welding stents, turning assembly fixture, industrial robots, precision rotary worktable, medical apparatus and instruments, measuring instruments, IC manufacturing equipment
