Tsubaki's new BB-2GD cam clutches offer increased service life and greater reliability in arduous environments thanks to a new lip seal design. The units are ideal for use in precision indexing, backstopping and overrunning applications in industries where contact with particulates may occur. Both standard clutches and internal keyway-mounted versions are available, which are easy to fit and interchangeable with competitive models as well as standard bearings (Plate 10).
OEM manufacturers producing equipment for woodworking, quarrying and materials handling industries are set to benefit most from Tsubaki's new range of sealed cam clutches. The lip seal on the BB-2GD series protects the internal mechanism of the clutch from dust, grit or other abrasive substances, benefiting users through improved performance in terms of durability and accuracy.

In addition to particulate ingress, contamination from foreign lubricants is also a common reason for premature clutch failure, especially during routine system servicing.To successfully combat this, the BB-2GD units come ready sealed with a long life lubricant, avoiding grease exchange as well as eliminating maintenance requirements.
The BB-2GD cam clutches are designed for convenient press fitting into standard ball bearing housings (from 35mm to 80mm OD) and can accommodate shafts from 15mm to 40mm. Torque capacities range from 29Nm to 260Nm allowing the units to easily replace bulkier, less efficient ratchet or roller designs in conveyor and vertical lift systems. For applications that require keyway fixing, Tsubaki also offers the BB-2GD-1K unit, which is available in a range of sizes and has a precision-machined keyway on the inner race.
Tsubaki are one of the few manufactures to carry this and several other models of precision clutch in stock ensuring immediate availability, rather than regarding them as "specials" that carry long lead times. The recent launch of other styles of cam clutch, such as the BB-K and BSEU series, means that they now offer one of the widest ranges of one-way cam clutches available, meeting torque requirements right up the scale to 686,000Nm.
