Conveyor Roller Bearing Housing – Conveyor Roller Cap:
In 60, 63, 76, 89, 108, 114, 127, 133, 159, 193mm diameter pipes 6204, 6205, 6206, 6304, 6305, 6306, 6308, 6310 type bearings are used as shown in the chart and we select Eregli (Eregli Iron and Steel Inc.) made deep sheet steel of DKP or HRP A1 and 6112-6114 quality in 2 – 3 – 3.5 – 4 – 5 – 8mm wall thickness for those bearings. The amount of slimming due to solid drawing on the steel sheet in the production of bearing housing – roller cap must be small and that must be checked. Engineering calculations in manufacture of the molding of bearing housings. Conveyor belt rollers caps should be very accurate in order that plastering phases in solid drawing can not cause slimming of the sheet. Otherwise there will be no clearance in the housing. In the bearing housing, fixing point of bearing housing should be in H7 clearance or tolerance. Otherwise, bearing won’t operate well, and in time, it will be locked, roller won’t turn, will be broken up and damage the belt. Insufficient care taken in adjusting clearances in bearing housing or sealing components in the bearing housing may cause revising the whole system. Required H7 clearance will be maintained during the process of bearing houses in CNC turning lathe after solid drawing of roller housings which were processed with having those clearances. ZC 3 type high rotational and temperature bearings are used especially not to be affected by the speed and temperature differences of operating conditions of roller housings. We fill them with Petrol Ofisi EP2 Super lubricating-grease to obtain isolation and seal the inside of bearings and plastics/aliminum labyrinths from air or blocking materials which cause them not to return like dust. Enduring to high temperatures and enabling long operating life for conveyor bearings thus for conveyor rollers, lubricant-grease we use is much more prefered.
