Bright Shaft and Roller

Bright Shaft and Roller (BSB) is a high-end shaft product launched by Wongsteel (Beijing Yijing Technology) for the precision manufacturing field. It is available in round, square, hexagonal and customized profiles, produced by precision processing technologies such as cold drawing, centerless grinding and peeling. With excellent surface finish, tight dimensional tolerances, high straightness and uniform mechanical properties, it has become the core raw material for precision component manufacturing, widely used in automotive manufacturing, general machinery, hydraulic systems, fasteners, tool manufacturing and other industries.

The product has comprehensive specifications: diameter/size ranges from 5mm to 100mm (standard for round shafts, other profiles can be customized), length from 2m to 6m (special lengths can be customized on request). Materials cover carbon steel, alloy steel, stainless steel, strictly complying with international standards such as ASTM, EN, JIS, meeting the strength, corrosion resistance and other performance requirements of different working conditions. The processing capacity is complete. In addition to basic processes such as cold drawing, peeling, grinding and polishing, it also provides deep processing services such as cutting, chamfering and threading, and supports customized heat treatment. The hardness, toughness and other mechanical properties of the shaft can be adjusted according to customer requirements, realizing one-stop customized delivery.

In terms of precision control, bright shafts and rollers reach industry-leading levels: diameter tolerance is controlled at h6-h11, straightness ≤0.1mm/1000mm, surface roughness Ra ≤1.6μm, which can perfectly adapt to high-precision assembly and processing needs, greatly improving the operational stability and service life of downstream products. The surface treatment solutions are rich, including bright polishing, black oxide, oiled protection, etc. Exclusive protection solutions can be provided according to the use environment, extending the anti-corrosion and wear resistance of the shaft.

Compared with ordinary hot-rolled shaft materials, bright shafts and rollers have higher dimensional accuracy, better surface quality, better machinability and uniform mechanical properties, which can effectively reduce downstream processing procedures, lower production costs, and improve product reliability and consistency. Wongsteel (Beijing Yijing Technology) can provide customized shaft solutions and comprehensive after-sales technical support according to customers' application scenarios, material requirements and precision standards, helping precision manufacturing enterprises improve their core product competitiveness.
