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.
Ball bearing stainless steel 1.4112.
Plain bearing insert POM.
Bushes and grease nipple stainless steel 1.4301.
Plain bearing insert white.
Stainless steel parts bright.
The housings are very robust, hard wearing and shock proof. They are resistant to most alkaline solutions, weak acids (PH 49) and brines. In contrast to cast or steel housings the special plastic in these housings prevent the formation of microorganisms.

Housing, stainless steel 1.4301.
Bearing, stainless steel 1.4125.
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.
Ballbearing steel 100Cr6.
Seal, rubber NBR.
Sealed on both sides with a spherical outer ring.
Can be relubricated.
The internal construction of the insert bearings corresponds to that of standard Series 6200 and 6300 radial ball bearing. However, they have wider inner rings for easier fastening on shafts. The inner rings are manufactured with a plus tolerance. This results in transition or press fits when using shafts with htolerances. The shaft is secured by 2 grub screws positioned 120° apart on the inner ring.
The insert bearings are ready to install and are permanently lubricated with a suitable ball bearing grease. In normal applications, relubrication is not necessary.
