Description
The B39R is an enhanced, heavy-duty classical V-belt featuring a wrapped, static-dissipating construction. The "B" indicates its cross-section profile, "39" designates its nominal inside length in inches, and the "R" typically signifies a reinforced or upgraded construction—such as the Timken Belts (Carlisle) Super II series—designed for high-stress industrial and agricultural applications.
Specifications
- Top Width: 21/32 in (commonly referred to as 5/8 in)
- Inside Length: 39 in
- Outside Length: 42 in
- Thickness / Depth: 13/32 in (approx. 7/16 in)
- Approximate Weight: ~7.68 oz (0.48 lbs)
- Industry Cross References: 5L420, B39, CARB39R
Features & Uses
- Built with premium polyester tensile cords and an EPDM rubber compound engineered to handle a broad temperature range (-50°F to 250°F).
The wrapped construction provides abrasion resistance making the belt more durable and provides protection against contamination.
- Formulated to satisfy rigid static conductivity and oil/heat resistance standards, preventing slips and heat buildup under high torque loads.
