RT310

RT310 (NEMA C) is a composite composed of a medium weave cotton reinforcement combined with a phenolic resin system. RT310 meets the requirements of MIL-I-24768/16, Type FBM. RT310 is designed for electrical and mechanical applications and is suitable for, gaskets, flanges, rings, collars, sleeves, pillow blocks, brake lining, timing wheels, light duty gears, journal and other bearing applications, and thrust washers. For increased dimensional stability, the grade is also offered in two heat treated versions, in an oven (H) or in oil (S), which improves the moisture resistance.

RT310H

RT310H (NEMA C) is a heat treated version of RT310, RT310H is a tube made from a medium weight canvas fabric combined with a phenolic resin that has good physical properties and machining characteristics. Typical applications include textile bobbins, lap spools and structural parts that require good impact strength. RT310H also complies with MIL-I-24768/16, Type FBM and ASTM D709 Type II Grade C.

RT310S

RT310S (NEMA C) is a hot oil treated version of RT310, RT310S is a tube made from a medium weight canvas fabric combined with a phenolic resin that has good physical properties and machining characteristics. Typical applications include textile bobbins, lap spools, and structural parts that require good impact strength. RT310S also complies with MIL-I-24768/16, Type FBM and ASTM D709 Type II Grade C.

RT315

RT315 is composed of a medium weave cotton reinforcement combined with a phenolic resin system, enhanced with a self-lubricating graphite powder modifier. The mechanical properties are similar to NEMA C. RT315 is designed for a variety of applications, including cams, gaskets, flanges, rings, collars, sleeves, pillow blocks, brake lining, timing wheels, light duty gears, journal and other bearing applications, and thrust washers. It is not recommended for electrical applications.

RT325

RT325 is composed of a fine weave cotton reinforcement combined with a phenolic resin system enhanced with a self lubricating graphite modifier. With mechanical properties similar to NEMA LE. RT325 is suitable for a variety of mechanical applications, but should not be used in electrical applications except as a static drain material, as it has the potential to be a conductor of electricity. NP325 is suitable for cams, gaskets, rings, collars, sleeves, brake lining, timing wheels, hydraulic rings, light duty gears, bearing retainers, thrust washers, and bearings.

RT342

RT342 (NEMA C) is composed of a medium fine weave cotton fabric reinforcement combined with a phenolic resin system. RT342 complies with the requirements of MIL-I-24768/16, Type FBM, and is designed for low voltage electrical and mechanical applications that require better machining than RT310. RT342 is suitable for cams, gaskets, flanges, rings, collars, sleeves, pillow blocks, brake lining, timing wheels, light duty gears, journal and other bearing applications, and thrust washers.

RT342H

RT342H is a heat treated version of RT342, RT342H is a fine weave canvas phenolic material with fabric construction weight intermediate to RT310 and RTB320. RT342H is designed for better machining than grade RT310 and lower cost than RTB320.

RT360

RT360 is a tube made from HEAVY weight canvas fabric saturated with a phenolic resin system, modified with molybdenum disulfide, that has good physical properties and machining characteristics. Typical applications include journal bearings and structural parts that require good impact strength and wear resistance.

RTB320

RTB320 (NEMA LE) is composed of fine weave cotton cloth reinforcement combined with a phenolic resin system. RTB320 meets the requirements of MIL-I-24768/13, Type FBE and is designed for electrical and mechanical applications that require fine machining. RTB320 offers low moisture absorption and excellent dimensional stability. It is suitable for cams, gaskets, rings, collars, sleeves, brake lining, timing wheels, and hydraulic rings, light duty gears, bearing retainers, bearings, and thrust washers. A variation of this grade comes heat treated in an oven (H) for increased dimensional stability.

RTB320H

RTB320H (NEMA LE) is a heat treated version of RTB320, RTB320H has low moisture absorption and excellent dimensional stability. Typical uses include retainers for ball-bearings and applications that require fine machining characteristics.

RTB320S

RTB320S (NEMA LE) is a hot oil treated version of RTB320, RTB320S has low moisture absorption and excellent dimensional stability. Typical uses include bearings and applications that require fine machining characteristics.

RTB320X

RTB320X (NEMA LE) is composed of an extra fine woven cotton fabric and of a phenolic resin system. The extra-fine weave fabric enables cleaner machining (less exposed fiber) in all relevant applications. It is a superior machining grade with very good electrical properties. RTB320X was developed specifically for the manufacture of bearing cages (ball bearing retainer rings).

RTB320Z

RTB320Z (NEMA LE) is composed of an extra fine weave woven cotton fabric with a phenolic resin system. While being similar to RTB 320X, enhanced machining characteristics are achieved by increasing the density of the manufactured tubes. Typical applications include retainer rings for ball bearings.
