Product Description

Tapered roller bearings are widely used in machine tool spindles, transmissions, automobiles, rolling mills, mining, metallurgy, plastic machinery, steel equipment, pump compressors, gear devices, paper machinery, railway vehicles, motorcycles, wind power generation, household appliances, electric motors , Pumps, machinery and other auto parts.


material

We usually use bearing steel (GCr15), but many manufacturers only use softer carbon steel materials, so our bearings have higher hardness and longer service life.

Heat treatment

We have our own heat treatment plant and do not need to be outsourced. We use a slower speed and more stable temperature to effectively control the steel and increase the toughness and life of the steel. Other small-scale bearing companies usually need to outsource. Many outsourcing factories only strengthen the hardness of the bearing surface due to cost factors, but the hardness inside is not enough, which is the reason why many bad bearings are easy to crack. Precision Our bearings can be controlled at a height accuracy of 0~-0.004mm, fast speed and smoothness.

Multiple grinding process

We grind the bearing many times, but others may grind it only once, so the chamfer of our bearing is very smooth. In conclusion We use high-quality materials and multiple grinding processes, so our bearings have the characteristics of high speed, low noise, high precision and long life.
