bearing feed раper photocopier is controlled by two which for a 1244 The rollers are sprung force of together with approximately 20N. The rollers each consist of a 20 mm outer a Steel shaft diameter plastic cylinder Plastic cylinder pressed onto a 10 mm diameter steel shaft (see Figure 9.30). The maximum feed rate for the Figure 6.30 Copier rollers. copier is 30 pages per minute. Select bearings to support the rollers.
