10 Caster Terminology Caster Size Same as Wheel Diameter Load Height Vertical distance from top plate to the bottom of the wheel. Offset Horizontal distance between the centerline of the swivel kingpin and the centerline of the axle. Raceway Surface on which bearing rollers or balls move. Spanner Bushing The fixed sleeve in which the axle runs. Swivel Radius Horizontal distance between the centerline of the swivel kingpin and the outside edge of the wheel. Thrust Washer The washer between the wheel hub and the inside of the caster horn leg. Tread Width (Face) Width of the wheel tread. Thread Guard Cover over the axle bolt and bearing raceway which helps to prevent thread and debris from wrapping around the axle bolt. Also serves as a dust cap to prevent dust and dirt from entering the axle bearing and raceway. Durometer (Shore Hardness) A measure of the hardness of rubber and other thread materials on the Shore A or D scale. Generally, the higher the durometer, the harder (or less resilient) the wheel tread material is. Rollability The ease with which a wheel or caster can be rolled. Rollability is affected by wheel size, type of tread, and bearings. The larger the wheel, the easier it is to roll. A hard narrow (donut) tread rolls easier than a flat soft tread on a smooth floor. Soft treads protect floors and roll over obstructions more easily. Metro uses three different types of plate casters: A Plate: (A5L/R/B.) Light duty caster and horn with plate measurements of 2-⅜ x 3-⅝ (60mm x 92mm). Bolt hole spacing is set at 1-¾ x 3 (44.5 mm x 76.2mm) for 5/1 (8mm) mounting hardware. B Plate: (B5P, B5DN, etc.) Heavier duty than A plate with plate measurements same as above. C Plate: (C5P, C8P, etc.) Heavier duty than both A and B plate with plate measurments of 3-7/ x 4-3/4 (98mm x 121mm). Bolt hole spacing is 3 x 3-7/ (76mm x 98mm) for 5/1 (8mm) diameter mounting hardware. BL Plate: (6P, BL6P, 8P, BL8P) Swivel/brake lock caster manufactured by InterMetro. The caster plate measures 3-7/ x 4-3/4 (98mm x 121mm) Bolt hole spacing is 3 x 3-7/ (76mm x 98mm) for 5/1 (8mm) diameter mounting hardware. Types Of Wheel Bearings: Plain usually a plain friction-type metal bushing or sleeve. Self Lubricating Bearings - usually a porous metal bushing permanently impregnated with oil (sintered iron), or an impregnated Dupont (Delrin) plastic bushing. Delrin bearings are suitable for corrosive environments (steam cleaning). Both bearings are designed for light load application. Ball Bearings - Used when maximum rollability is required. Designed for heavier load applications than self-lube bearings. Roller Bearings Used when greater load capabilities and rollability are required.

11 Caster Wheel Tread Materials Solid Soft Rubber (A5L, A5LR, A5LB) a solid resilient rubber offering maximum floor protection quiet operation at low cost. It will not withstand heavy loads or exposure to grease and oil. Rollability is fair, and soft rubber will take on a permanently set flat spot if left loaded in one position for days at a time. May mark certain floors. Solid Hard Rubber (B3, B3B, B3R) - a solid hard rubber offering higher load rating and better rollability than soft rubber, but it is noiser and offers less floor protection. Neoprene ( B5DN, B5DNB, B5DNR) - A type of resilient rubber able to withstand most commonly encountered greases, oils, and alkalis. It offers good rollability and generally good operating characteristics for many applications. May present temperature limitations for some applications. Polyurethane (B5P, C5P etc.) A synthetic elastomer with significant resistance to temperature, shock, fuels, oxidation, detergents, and oils. It offers long life with the wear resistance of hard rubber and the resilience of soft rubber. Polyurethane wheels are non-marking and quiet in operation. Hi-Temp Phenolic A compression molded thermoset resin and macerated canvas wheel which is able to withstand temperatures from -40 F to 475 F (-40 C to 246 C.) Phenolic wheels offer greater load bearing capacity, ease of rollability, and better resistance to oils, fats, and chemicals. Phenolic wheels, however, are noisier in operation, and more susceptible to wear, chipping, and gouging. Often specified for freezer and hi temp/autoclave applications. Cart wash/autoclave applications require stainless version (custom). Solid Polyolefin A lightweight, hard, non-marking, impact resistant, and easy rolling wheel made from thermoplastic resin. Polyolefin wheels offer good resistance to oils, grease, solvents, acids, and other chemicals. Polyolefin wheels, however, tend to be noiser in operation than softer wheel materials. Hi-Modulus Rubber (C6DA, C8DA Advantage etc.) Special modulus thermoplastic rubber which offers superior rollability and maneuverability. It carries large loads while offering shock-absorbing protection to the equipment. Advantage wheels are virtually nonmarking, quiet, and will withstand all common cleaners, solvents, acids, oils, and chemicals, and frequent cart washings. Pneumatic (C8AIR, C8AIR-R) Inflatable resilient rubber tire offers the greatest protection to loads and floors. Good selection for use over rough terrain where maxiumum load protection is required.

12 General Rules of Caster Application The total weight of the equipment and its load should never exceed 3 times the caster load rating. Always consider the weight of the equipment + the load being transported when selecting caster load ratings. Given the same wheel material, the larger the wheel diameter, the greater the load capacity, and the better the rollability. A minimum of a wheel should be used when floor surfaces are rough, or when door or elevator thresh holds are present. Roller bearings and ball bearings have greater load carrying capacity than engineered plastic bearings or sintered iron bearings. Under heavy loads, harder tread materials will roll and swivel the easiest, and traverse uneven floors and obstacles the best. Under light loads, soft tread materials offer advantages on uneven floors, while maintaining acceptable levels of rolling and pivoting resistance. Additionally, harder tread materials perform better on soft or smooth floors, and soft treads roll better on hard or rough floors, including most outdoor surfaces. For a given material, wheels with wider flat-face treads will carry the greatest load and last longer. Wider, flat-face treads also give you an advantage in overcoming rough surfaces. Narrow (donut) shaped wheel treads however; will swivel easier, especially on carpets. Rubber, especially hi-modulus rubber and pneumatic tires will give the quietest movement and maximum floor protection, while phenolic and polyolefin is hardest on floors. Polyurethane is frequently an effective compromise, giving moderate floor protection with greater load capacity than rubber. Never use a soft rubber caster wheel in a corrosive environment or a cart wash application.
