Grey cast iron - Import export

Reference surfaces precision machined Note: Ring bolts for lifting are supplied. A cover prevents the cavities filling with swarf. Drawing reference: machined faces: +0.2 mm/ +0.5 mm unmachined faces: ±2 mm

Grid spacing 50 ±0.02 mm. Tombstones with grid holes are used on horizontal machining centres. The alphanumerically labelled grid holes guarantee a defined assignment of clamping elements by repeat setups. The tombstones conform to machine tables for machine tools acc. to DIN 55201 and JIS 6337-1980. Please order locating pins for positioning subplates on machine tables acc. to DIN 55201 separately. Please order protection plugs to plug unused grid holes separately. Ring bolts for hoisting are supplied. Other dimensions available on request. Drawing reference: 1) grid hole 2) hole for DIN 912 cap screw (D3/D4)

Round baseplates with T-slots are used for constructing modular fixtures. These baseplates are positioned and mounted directly on machine tables. The precise longitudinal and transverse slot spacing ensures very high repeat clamping accuracy. The aligning holes are used to align the baseplate on the machine table. Please order locating pins to locate the baseplates separately. Ring bolts with T-nuts for hoisting are supplied. Other dimensions available on request. On request: other dimensions. Drawing reference: 1) hole for DIN 912 cap screw (D4)

Housing, grey cast iron. Bearing, ballbearing steel 100Cr6. Seal, rubber NBR. Pillow block bearings consist of a sealed singlerow ball bearing with a spherical outer ring which is mounted in a housing. Because of the spherical outer surface of the bearing, shaft misalignment can be compensated for. The bearings are manufactured with a plus tolerance. This results in transition or press fits when using shafts with htolerances. The shaft is secured by grub screws on the inner ring. In normal applications, pillow block bearings are maintenancefree due to the lifetime lubrication. In difficult environmental conditions relubrication can be carried out over the grease nipple. All housing dimensions are nominal dimensions for which the usual casting tolerances must be taken into consideration.

Steel C45. Grey cast iron GG22 from 38 teeth. Sprockets with hub one side for DIN ISO 606 roller chains. The sprockets have a centre bore or are predrilled (this can vary due to production methods). For this reason, the dimension D3 max. given in the table is the maximum diameter of the bore that the sprockets are supplied with. This pilot hole/centre bore can be customised with a reamed hole, reamed hole with keyway or a tapped hole by the customer. Alternatively, bushes can be fitted by the customer to reduce the diameter.
