Product Description:
Beckhoff designed the ZK7208-3031-A050 as a specific motor cable for use in industries.
The cable is built to drive high-performance motion control technology while using a ball bearing system for better mechanical reliability and attachment. This combined design works best for systems that need both electrical and mechanical precision in automated devices and computer numerical control mechanics. The integrated bearing system measures 40 mm internally, 68 mm outside, and stands 15 mm tall. The specialized design with a 30-degree contact angle lets this product support loads in both axial and radial directions. The bearing operates with a brass cage known for handling heavy loads and extends a P5 precision level to provide reliable angular positioning. This bearing demonstrates operational excellence by handling dynamic loads to 21,200 N plus static loads of 13,300 N across challenging movement tasks. Grease and oil lubricated models enable smooth operation at 10,000 rpm and 14,000 rpm, respectively, because of the bearing's durable function at high speeds.
The design uses one bearing row arranged in an open space and wirelessly connects to the mounting for effortless installation. This motor cable uses electrical engineering to produce versions that handle dynamic tasks well. The cable maintains 77mm of minimum dynamic bending, which gives it seven times the tolerance of its external size for effective drag chain operations. The cable holds up well against 3 million mechanical bends while being perfectly designed for moving equipment that needs extended service time. This Beckhoff product combines motor cable technology with bearing capabilities to support automation system requirements. It can be purchased at Wake Industrial with a one-year warranty.
