Du bushing
The Du bushing from Jiashan Pvb Sliding Bearing Co., Ltd is a steel-backed self-lubricating component designed for low-friction, maintenance-free operation in mechanical assemblies. It features a composite structure with a carbon steel outer shell and a sintered bronze inner layer, with no PTFE overlay mentioned in the source. Dimensions are available in standard sizes to fit common shaft diameters from 6 mm to 80 mm, with wall thicknesses of 1.8 mm to 3.2 mm.
The bearing relies on the inherent lubricity of bronze and its porous structure to retain and release lubricants under load, a typical design for non-PTFE self-lubricating bushes. This differs from PTFE-lined variants by requiring occasional lubrication in high-speed applications. The material complies with ASTM B619 for sintered bronze, and the steel backing meets ASTM A108 for cold-drawn carbon steel, ensuring dimensional stability under thermal stress.
These bushings are used in agricultural conveyors, hydraulic cylinders, and small electric motors where cost-effective maintenance reduction is prioritized over extreme temperature performance. They are supplied in bulk cartons of 200 - 1,000 units, with paper dividers between layers. Trade terms include FOB Ningbo, with lead times of 20 - 30 days. MOQ is generally 2,000 pieces per size, though partial shipments may be arranged upon direct negotiation.

Sourcing Du bushing from Jiashan Pvb Sliding Bearing Co., Ltd - China Import Guide
Before ordering, verify the bronze alloy composition and porosity level through a material test report. Confirm bore and outer diameter tolerances match your housing and shaft dimensions with a clearance of 0.05 - 0.1 mm. Request a sample to test for surface finish and lubricant retention under simulated load conditions.
Confirm lead time is 20 - 30 days from order placement, and agree on Incoterms such as FOB Ningbo. Payment terms are typically 50% advance, 50% before shipment. Packaging includes paper dividers between units to prevent scratching - ensure no plastic wrap is used, as it can trap moisture. Request a packing list with batch numbers and material certifications.
Perform incoming inspection using a micrometer for bore size and a hardness tester for the bronze layer. Check for surface cracks or uneven sintering by visual inspection under 10x magnification. Request a certificate of conformity referencing ASTM B619 and ask for batch-specific test data on load capacity and friction performance under lubricated conditions.
