Self Lube Rollerless Chain SL

Product catalog summary

Overview: The document provides technical specifications for SY type rollerless chains, specifically the SL type, which are bushed chains made without rollers. These chains are designed for specific applications and have unique lubrication requirements.

Specifications: The document lists various dimensions and mechanical properties for different chain models, including pitch, bushing diameter, pin diameter, plate dimensions, tensile strength, and chain weight. Each model is identified by a specific code (e.g., SY 40-1 SL, SY 50-2 SL) and has distinct measurements.

Key Features: - SL type chains use a one-piece oversized sintered bushing that contains extra oil volume, ensuring lubrication in critical areas. - Chains are lubricated before delivery. - Connecting links are of the "cotter" style for sizes above 100 SL.

Limitations and Recommendations: - Service life is significantly reduced if the lubricant in the oil-impregnated bushings is depleted. - Operating temperatures above 70℃ cause rapid depletion of lubrication. - Not suitable for environments exposed to chemicals, water, or shock loads. - Wet or dusty conditions may lead to premature wear.

Applications: The chains are suitable for specific applications where lubrication is critical, but they are not recommended for environments with harsh conditions or where exposure to chemicals and water is expected.

Catalog excerpts

Self Lube Rollerless Chain ANSI | Single Pitch | Lube Free | SL “SL” type rollerless chains are made with a one-piece oversized sintered bushing. The sintered bushing has extra volume of oil and keeps lubrication in the critical bearing area of the pin and bushing where it is needed most. “SL” type rollerless chain is lubricated prior to delivery. Average Tensile Strength SL type chains are a bushed chain which made without rollers. Connecting links are “cotter” style for all sizes above 100 SL. Consult SUGIYAMA for offset links. Service life decreases dramatically if the lubricant in the oil-impregnated bushings is depleted. The lubrication in the oil-impregnated bushings will seep out rapidly when the operating temperature exceeds 70°C. A wet or dusty environment may lead to premature wearing. It is not recommended for applications which are exposed to chemicals or water, or associated with a shock load.
