LogiMAT 2020
Useful rolling helpers from Dr. Tretter
Dr. Tretter's range of ball transfer units and tolerance sleeves will be on display at Logimat. The design components are used in conveyor systems such as roller conveyors or ball transfer tables.
The ball transfer unit consists of the track ball and a large number of small load-bearing balls. A hardened support shell serves as the raceway. This design allows the track ball to rotate in all directions with low friction. The support balls roll in the shell as the track ball rotates. Several ball rollers are arranged on one level. This allows even heavy loads to be turned or moved effortlessly - up to 14 tons depending on the size. Tolerance sleeves are slotted sheet metal sleeves with beads that are embossed like shaft crests. The standard material used is stainless spring band steel, which can withstand temperatures of up to 250 degrees Celsius. Special versions can even be used at temperatures of up to 450 degrees Celsius or in aggressive chemical environments. Tolerance sleeves are used, for example, in conveyor technology for fastening idlers.
