Lovejoy catalog number 69790400042 is a C 7/8 Sleeve, an elastomeric component for S-Flex couplings. This sleeve, sourced from Lovejoy-Werdohl, is designed to wrap around hub lugs, providing torsional flexibility and damping for misalignment in power transmission systems. It is compatible with corresponding S-Flex coupling hubs to create a complete, maintenance-free assembly suitable for various industrial applications.

Continuous Sleeve Series

Features:

• Simple and inexpensive all steel type of gear coupling constructed with a single sleeve and 2 hubs
• Comparatively simple installation
• Precision cut 20° pressure angle gear teeth with minimum backlash
• Most standard configurations are available as stock items
• Angular misalignment of 1/2° per gear mesh (flex-plane)
• Sizes 7/8 through 12, to accommodate bore sizes up to and including 12.50 inches
• Interference fit (standard) and Clearance fit on bores are available
• Load Capacities range from 2, 500 in-lbs up to 2, 520, 000 in-lbs
• Designs for applications requiring horizontal and vertical orientation, full-flex, flex-rigid, mill-motor, disengagement, sliding hubs, Shear Pin, floating shaft, and spacers
• Patented and tested BUNA N seal design with reinforced washers bonded to the inside edges which positively retain lubricant and seal the interior from outside contaminants

Standard Types and Sizes

Lovejoy / Sier-Bath couplings are stocked in an assortment of configurations which include C and F standard hubs and sleeves, Mill Motor hubs, Vertical style, Floating Shaft, and Spacer designs. Lovejoy’s superb engineering staff make it possible to support many additional coupling types such as the Brakedrum type, Sliding Hub type, Shear Pin type, Jordan type, and custom lengths for non standard shaft separations. Additional size ranges and designs to meet unusual application requirements can also be manufactured by Lovejoy to meet market demands. Material can range from standard steel to alloy steel and even stainless steel. The exceptional simplicity of the Lovejoy coupling design make this all possible.

C Type Flex-Flex Couplings

The C Type coupling consists of two flex hubs, one sleeve and one accessory kit consisting of seals and snap rings.
