"We work with leading trailer axle manufacturers. The axles are produced in Shandong, China. By doing our own manufacturing, we control the production quality and costs. The end one-piece product (without welding) is very strong and durable, as the manufacturing process is high- tech and precise," said CPC Marketing General Manager Desmond Lim.
The unique one-piece, specially heat-treated, low-alloy lighter weight compared with conventional axles.
The integral “P” type swage straight spindle or tapered spindle with induction – hardened bearing journals - pro- vides superior fatigue capability. The trailer axle spindle was also processed by a digitally controlled lathe machine.

CPC mechanical suspensions
Meanwhile, the CPC 14-tonne and 16-tonne mechani- cal suspensions come with hanger brackets (7.75mm to 8mm thickness) that were welded using automated robots for consistent quality. The mechanical suspensions also come with 25mm variable height spring seats for trailer slope design, high quality leaf springs as well as a 60mm diameter equaliser pin with bronze bush.
CPC over-slung air suspension
As for the CPC over-slung air suspension, its necked-in hanger bracket gives improved hanger/chassis connec- allowing welding to narrow chassis rails, chassis friend- ly connection, and ease of bracing connection. Its trail- ing arm uses SUP11 material grade that provides higher weight savings.

The suspension dampers have a heavy duty (double- acting) design, and the integral check strap is rated at 10 tonne per damper. As a result, there is less road
