What is the fitting clearance of the track roller bushing of a crawler crane?

Crawler crane roller bushings generally use bimetallic bushings. This bimetallic bushing is mostly used in the form of internal and external grinding. The fit between the bushing and the shaft is a clearance fit, and the clearance is generally about 10 wires, because The bearing capacity of the crawler crane's rollers is relatively large, and perhaps the gap can be larger. This bimetallic bushing generally uses a low-carbon steel plate as the base material, and is a steel-copper alloy product with CuPb10Sn10 or CuSn6Zn6Pb3 materials sintered on the surface. The balance bridge bushing of this heavy-duty vehicle is the one with the strongest load-carrying capacity among double alloy bearings. It is a high-load, low-speed motion bearing with a wide range of uses.
