Providing continuous lubrication is always the best way to maximize chain life.  However, for an application that must be clean and free of oil and grease, or is difficult to access for maintenance, or requires saving on the cost of daily lubrication, or requires the longest chain life, TYC provides a complete package of solutions, including SL, SLB, SLH and O-ring series chains.  These products are suitable for both driving and conveying applications.

Self-lubricating (SL) chain is a regular sintered-bushing chain designed for normal operating conditions. The chain tensile strength is lower than ANSI standard roller chain.

SLB (SLB) chain is designed with the same tensile strength as ANSI / ISO standard chain, and is good for moist situations because the sideplates and pins are coated. SLB chain is especially a good choice for conveying applications because it has rollers assembled. TYC has a variety of chain sizes and attachments available for your different needs.

SLH (SLH) chain has the same features as SLB chain, and it is designed with the same maximum working load as ANSI standard roller chain. It works well in drive
applications at low to moderate speed. For usage in high speed or high load applications, consult TYC for more information.

O-ring (O-ring) chain has seals which keep high quality lubricant in and keep dirt and other contaminants out of the chain's bearing area. It is the longest lasting type
of lube free chain, especially in agricultural harvesting equipment.
