Gates® Power Transmission Hi-Power® II BB277 Banded Heavy Duty Double V-Belt, BB Section, 21/32 in W Top, 278 in L Outside, 17/32 in THK, EPDM
Designed with a unique recessed top and bottom to maintain sidewall contact, while remaining flexible for belt drive applications that require power transmission from both sides of the belt.
PowerGrip™ HTD belts have a larger, more robust tooth profile for increased capacity, as compared to timing belts. 3M and 5M belts are suitable for domestic appliances, office machines, electric hand tools and for applications in the processing and chemical industry. 8M, 14M and 20M belts are used in high-performance drives in the machine tool, paper and textile industries where durability and low maintenance are required.
Gates® Power Transmission Hi-Power® II B65 Banded Heavy Duty V-Belt, B Section, 21/32 in W Top, 68 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.
Gates® Power Transmission Hi-Power® II B57 Banded Heavy Duty V-Belt, B Section, 21/32 in W Top, 60 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.
Developed by Gates and produced to patented manufacturing processes, these belts provide more load-carrying capacity at higher speeds to small multiple V-belt precision drives. This results in significant cost savings and improved design freedom.
Smith Bearing® HR-3/4-XB Cylindrical Stud Type Needle Bearing Cam Follower, 3/4 in Dia x 1/2 in W Roller, 7/16 in Dia x 7/8 in L Stud, 52100 Steel Roller
The HR Series have a larger diameter stud and are recommended for applications with high running loads and/or heavy shocks where deflection should be held to a minimum. Rollers and outer races are identical to the standard CR Series. Manufactured from high alloy bearing quality steel.
