Boston Gear Entries

  • ►  Bearings • Pillow Block Bearings 

    For: Entry

    Pillow block bearings are mounted roller or plain bearings for supporting a rotating shaft with the mounting surface on a parallel line with the axis of the shaft.

    Boston Gear offers a large selection of mounted pillow blocks and flange units that include washdown duty service using non-metallic inserts in a non-metallic base or eccentric locking collars in ductile iron, stamped steel or cast iron housings. Features include synthetic lip-type seals with steel flingers. Other products offered include ball and linear bearings.

  • ►  Bearings • Ball Bearings 

    For: Entry

    This design reduces friction, as the fixes race stays in place while the free race spins around the rotating balls.

    Boston Gear are manufacturers of unmounted, inch size ball bearings available in radial and thrust designs. Features include double sealed and double shielded grease packed bearings for greater versatility. Applications include flanged, banded, rope or wire, chains or belts, and flange mounted. Other types of bearings offered include plain sleeve, mounted, molded plastic, thrust, rod ends and sphericals, and linear type.

  • ►  Bearings • Plastic Bearings 

    For: Entry

    A wide variety of bearing types can be made from plastic when a specific application calls for nonmetallic bearings.

    Boston Gear stocks a wide selection of molded plastic bearings in Nylon, Delrin, Nylatron and Teflon. These products require no lubrication, increasing efficiency and reducing maintenance needs. They are resistant to moisture and chemicals and will not contaminate their surroundings.

  • ►  Bearings • Thrust Bearings 

    For: Entry

    Thrust bearings are a type of rotary bearing. Like other rotary bearings they permit rotation between parts, but can simultaneously support a high axial load.

    Boston Gear builds hardened steel and stainless steel thrust bearings for high load capacities.The thrust ball bearings are offered as ground & unbanded or unground & banded (600 series). The ground and unbanded line has the AO series that are hardened alloy steel and the SAO series that are hardened stainless steel.  Hardened steel balls are maintained in a nylon cage to increase efficiency and durability while decreasing friction loss. The unground, banded series are of full ball type (v) without a retainer.

  • ►  Bearings • Rod End Bearings 

    For: Entry

    A rod end bearing, also known as a helm joint, is a mechanical articulating joint used where a precision articulating joint is required.

    Boston Gear are producers of rod ends and spherical bearings for applications that use linkages where a bearing accommodates significant misalignment under heavy radial or thrust loads. Rod ends are available in both left and right hand designs, as well as in either male and female threads. Spherical bearings are mounted in a pre-designed housing. Self lubricating liners are available. Other products offered by Boston Gear include molded plastic, ball and thrust bearings.

  • ►  Bearings • Linear Bearings 

    For: Entry

    There are many different types of linear motion bearings and which can be broken down into either rolling-element or plane bearing varieties.

    Boston Gear offers four series of linear bearings, including precision, commercial, open and instrument types. The precision and open series' are available in either stainless steel or steel. They are also available with or without an integral seal for operation in contaminated environments.

  • ►  Power Transmission • Couplings 

    For: Entry

    A coupling is a mechanical connection that brings two shafts together at the ends to allow transmit power from one rotating shaft to a non rotating shaft.

    Boston Gear offers a wide range of couplings for the following applications: packaging equipment, material handling, gear boxes, compressors, pumps, and machine tools. Coupling types include rigid, clamping, plastic, multi-jaw, shear, and 3-jaw spider/insert. They come in bore sizes ranging from 1/8" to 2" and horsepower ratings ranging from 1/2 to 115.9 RPM.

  • ►  Power Transmission • Shaft Collars 

    For: Entry

    Shaft collar is a simple machine component found in motors and gearboxes. The collar is a mechanical stop that locates components and bearing faces.

    Boston Gear's shaft collars are available in several configurations. The setscrew collar is for simple positioning on a shaft. The threaded clamp collar provides a higher axial holding force. The 1-piece clamp collar provides a more uniform holding force on the shaft. The 2-piece clamp collar provides a higher and more uniform holding force.

  • ►  Power Transmission • Timing Belt Pulleys 

    For: Entry

    Timing belt pulleys are the component of the timing system that drive the pulley belt to complete the timing belt motion.

    Boston Gear's HTD® timing belts feature a lack of slippage, minimal amount of belt tension, and reduced bearing loads without requiring the need for lubrication. The line of timing belts are made of neoprene, covered in nylon and reinforced with fiberglass. The temperature of timing belts range from -18°C to 85°C with a belt speed of 6500 FPM Max. Timing belts of 3mm pitch are offered in a width size of 6mm and 9mm with a braking strength of 74.4 kgs and 111.6kgs respectively. Timing belts of 5mm pitch are offered in a width size of 9mm and 15mm with a braking strength of 234 kgs and 390 kgs respectively.
