Who We Are
PTB Bearing Factory is a tapered roller bearing manufacturer based in China.
We produce and supply tapered roller bearings for replacement, maintenance, and OEM applications, covering common inch and metric series.
Manufacturing, stock preparation, and export arrangements are handled internally, which allows us to keep stable quality and practical delivery schedules.
By working with one bearing category only, we are able to control dimensions, fit, and running performance consistently from batch to batch.
