Rod End Bearings Information

FEATURES AND BENEFITS

THREE-PIECE ROD ENDS Sealmaster three-piece rod ends incorporate a one-piece race formed around a hardened steel chrome plated ball in a controlled manufacturing process. Three-piece construction offers flexibility for alternative race materials designed to help solve specific application problems. Consult Application Engineering for material combinations available to meet your application needs.

MACHINED STEEL HOUSING • Protective coated for corrosion resistance • Higher average tensile strength and fatigue life vs. competition • Wrench flat on female rod ends facilitates assembly • Full catalog thread depth for maximum thread engagement

ONE-PIECE RACE • Reduces pound-out in applications with high frequency oscillation, vibration or shock loading • Improved spherical ball-race conformity for even load distribution • Precision ball-race fit • Less wear than rod ends with two-piece race designs • Manufactured in steel, aluminum bronze and self lubricating Delrin BALL • Alloy steel heat treated and chrome plated for corrosion resistance • Better wear resistance properties than carbon steel tin nickel plated balls

TWO-PIECE ROD ENDS Sealmaster two-piece design rod ends consist of a machined housing formed around a hardened steel chrome plated ball. This construction offers more load capacity than three-piece designs with like housing materials because of greater housing cross section.

MACHINED STEEL HOUSING • Protective coated for corrosion resistance • Wrench flat on female rod ends facilitates assembly BALL • Alloy steel, heat treated, chrome plated for wear resistance properties

MULTIPLE CONFIGURATIONS

SEALMASTER AR, ARE AND ARE-20N PRECISION SERIES EXTRA CAPACITY ROD ENDS • Three-piece design rod ends with heat treated alloy steel housing for high static, radial loads. The construction also helps reduce ""pound-out"" in applications with high frequency oscillation, vibration or shock loading. • One-piece carbon steel outer race with protective coating for corrosion resistance • Alloy steel, heat treated, chrome plated ball for wear resistance properties • Wrench flat on female rod ends facilitates assembly • Bore sizes form 3/16"" to 3/4"" • Grease fittings available on ¼"" through ¾"" bore sizes • Male and female versions with right and left hand threads • The ARE-20N Series offers an oversized shank for additional shank strength

SEALMASTER CFF-T AND CFM-T PRECISION TWO PIECE ROD ENDS • Two piece construction with self-lubricating PTFE liner for applications where grease lubrication is not practical or desirable • Manufactured with consistent, no load, rotational torque values for accurate linkage control • Machined carbon steel housings with protective coating for corrosion resistance • Alloy steel, heat treated, chrome plated ball for wear resistance properties • Wrench flat on female rod ends facilitates assembly • Bore sizes form 3/16"" to 3/4"" • Male and female versions with right and left hand threads

SEALMASTER TR AND TRE PRECISION SERIES ROD ENDS • Three-piece construction to help reduce “pound-out” in applications with high frequency oscillation, vibration or shock loading • One-piece carbon steel outer race with protective coating for corrosion resistance • Alloy steel, heat treated, chrome plated ball for wear resistance properties • Wrench flat on female rod ends facilitates assembly • Bore sizes from 3/16"" to 1"" • Grease fittings available on ¼"" through 1"" bore sizes • Male and female versions in both right and left hand threads

SEALMASTER TF/TM, CFF/CFM, CFTD, CTMD COMMERCIAL SERIES ROD ENDS • Two and three-piece design • Variety of material and construction combinations • Machined carbon steel housings with protective coating for corrosion resistance • Alloy steel, heat treated, chrome plated ball for wear resistance properties • Wrench flat on female rod ends facilitates assembly • Bore sizes from 3/16"" to 3/4"" • Grease fitting available on CFF/CFM and TF/TM series in 1/4"" through 3/4"" bore sizes • Male and female versions in both right and left hand threads TF AND TM • TF and TM series is designed with one-piece bronze race for lower coefficient of friction. CFF AND CFM • CFF and CFM series with two piece construction has a greater housing cross section and increased load capacity than three piece rod ends with like housing materials. • The commercial CFF, CFM series provides a lower cost alternative to the precision grade three piece rod ends with like housing material. CTFD AND CTMD • CTFD and CTMD series with self-lubricating Delrin* race for light duty applications where oil and grease should be avoided. • The rod end utilizes a DELRIN acetal resin race material with lower coefficient of friction than metal to metal versions. • Delrin material withstands vibration without galling or fretting and absorbs little moisture compared to bearings with nylon races.

SEALMASTER ROD ENDS WITH Y-STUDS • Y-studs are available on Sealmaster TR/TRE, TR-N/TRE-N, CFF/CFM, CFF-N/CFM-N and CTFD/CTMD rod ends bore sizes from 3/16"" to 3/4"". • They are designed to facilitate right angle connections and accommodates up to ± 25 degrees of angular misalignment in any direction. • The Y-stud contains a hex wrench flat to facilitate assembly advantages and are manufactured from carbon steel and plated for corrosion protection. • Caution when selecting rod ends with Y-studs: Catalog load ratings are not applicable with Y-studs because of the reduced stud strength due to bending.
