- Flex-bonded cords are strongly bonded to the body of the belt resulting in equal load distribution and the absorption of bending stress without cord deterioration
- Notches molded into the belt during manufacturing increase flexibility making this belt well suited for drives with smaller diameter sheaves
- Belt edge is machined for even sheave groove contact resulting in smoother running, less slip and wear
- Patented ethylene material construction provides -60 to 250 deg F temperature range to resist belt cracking

Gates® Power Transmission Hi-Power® II B293 Banded Heavy Duty V-Belt, B Section, 21/32 in W Top, 294 in L Outside, 13/32 in THK, EPDM
The wrapped classical section Hi-Power™ V-belt has a long reputation for reliability on agricultural and industrial applications. The arched top of the Hi-Power belt provides superior strength to prevent "dishing" and distortion of the tensile section. The cords are properly aligned, each of them carrying its full share of the load.
Dichtomatik 75102143 O-Ring, 221 Dash Number, 1.421 in ID x 1.699 in OD, FKM, 75 Shore A Durometer, Import, Custom 221-viton
O-rings are closed circular rings of circular cross-section. They are made through vulcanization from form tools as a complete ring. The sealing function of the O-ring is achieved by the deformation of the cross-section when installed and compressed in its housing. The O-ring can be compressed either radially or axially in its installation housing. In operating conditions the pressure exerted by the media reinforces the sealing function, as under pressure the elastomer material functions as a non-compressible fluid.
