Keyways are British Standard Metric B S 4235. Part 1: 1972 DIN 6885 and conform to ISO recomendations with the exception of those marked, which are shallower. Where a key is to be used it should be parallel and side fitting, with top clearance. Depth of keyway is measured at the CENTRE
SITEX® gear couplings consist of two toothed hubs which are connected with one internally toothed sleeve. The hubs are made of steel and the teeth, which are both profiled and section crowned, are obtained from milling. The sleeve is manufactured from stabilized 6.6 superpolymade resin.
TRASCO® ES is our zero backlash coupling designed to compensate for misalignment and vibration dampening for indexing applications. The compact design of TRASCO® ES makes it the right choice for all precise motion applications.
The TRASCO ES consist of two hubs, which are either made of high-strength aluminium (up to the 38/45 size) or steel (from size 42) that are connected with an elastic element.

HRC couplings offer a range of hub and element selection to meet the demand for a low cost, general purpose spacer type flexible coupling. They allow for incidental misalignment, absorb shock loads and dampen out small amplitude vibrations. They are offered in both pilot bore, finished bore, Finished bore, and Taper bushed with both face and hub mount.
SIT TAPER LOCK BUSHING is designed to give the following:
1. Perfect assembly
2. rapid dismantling of the pulley and other transmission equipment
3. No special tools requirement except hexagonal key
The large range of finished bores available ensures that an immediate assembly can be made thus avoiding costly factory down-time.
Here are the dimensions of Taper Bushing with type 1210 (30.25)
- Bore : we provide taper bushing with minimal bore 12 mm and 5/8 inches; for the max bore you can look at the number writen after "BC" in every product name.
for example, BC3025F12 (1210X12MM), so the max bore is 30 mm.
- Width : the numbers writen in every product name before "F" is width size.
for example, BC3025F12 (1210X12MM), so the width is 25 mm.
- Bore size : look at the last number in every product name.
