Straight Roller Bearing Assembly includes a split outer raceway, steel rollers held parallel to the axle by a steel retainer, and end washers. A steel sleeve that fits over the axle is recommended.

Tapered Roller Bearings includes two bearings per wheel that ride directly on the axle.

There is no single formula that is valid in every situation for the selection of a caster. There are; however, standards established by the members of the Caster and Wheel Institute, a division of the Materials Institute of America which greatly facilitate caster selection according to class of service, component function and wheel application. Bond adheres to these standards in the classification and presentation of its casters.

Bond casters are used universally throughout industry and their applications are broad as they are varied. Standard Bond casters are available with wheel diameters ranging from 2" to 12" and in capacities from 75 to 6,000 lbs. per caster. Custom products can be produced outside of this product range for instance; custom wheel's can be as small as 1-5/8" or as large as 20". Custom casters can range from 30 to 20,000 lbs capacity.

Caster construction and wheel treads take into consideration intermittent as well as continuous service over the widest variety of floor surfaces. Bond capacity ratings were arrived at through a continuous testing and evaluation program and may be relied upon as a valid comparison of the relative performance values of the casters offered. However, due to the multiple variables in caster application, the users experience and knowledge of his operating environment must be an important consideration in the selection of a caster to meet an individual requirement.

Primary Features for Caster Selection

Mounting height is the distance from the top of the plate to the floor. If a stem caster is used it is the distance from the insertion point of the mounting leg to the floor.  This is used to design carts and to purchase truck locks.

Swivel radius is a measurement used to insure the caster remains under the cart or does not interfere with legs or skirts.

Offset is a measurement used to define the angle of the fork. A longer offset is easier to swivel.

Wheel Diameter and wheel width define the wheel size used to chose the correct

caster dimensions.

This illustration identifies the major caster features requiring consideration in caster selection. Dimensions for these specifications appear in the specifications for each caster.

LOAD - the load is comprised of the net weight of the material or equipment to be transported plus the weight of the vehicle, frame or other apparatus used in the conveyance.  This total weight is then divided by the number of casters necessary for the mobility and maneuverability desired.  The result is the caster capacity necessary to safely move the load.  A size larger caster may be advised if the floor is rough or uneven or contains other impact causing obstacles.

TYPE OF SERVICE – Intermittent? Continuous? Manual or mechanically powered? Each requires separate consideration. Occasionally moved loads, short travel distances or for dollies used to move material in storage or warehouse operations, a single ball race caster with or without anti-friction wheel bearings could be the wise and least expensive choice.  For continuous service, either manually or mechanically powered, a heavier duty double ball race caster with anti-friction wheel bearings is indicated.  Mechanically powered trailer-type operations require special heavy duty construction with large swivel bearings to withstand the impact and shock encountered. Bond casters and wheels are listed by the weight classification. You will find this

useful as an excellent aid for preliminary determination.  Complete details and specifications on each series should be referred to in making your final determination.

WHEELS – TREAD, DIAMETER, FACE – Wheel selection must be made with great care for it can not only determine the life of the caster but the life of the floor over which it travels.  Floors are expensive and therefore, must receive primary considerations – click here – to return to the wheel selection guide.  Other tips on wheels.  Large wheels roll easier than small wheels.  Hard treads roll easier than soft treads. Resilient treads roll over rough surfaces more easily than hard treads. Larger wheels mean larger bearings …longer life and easier rolling.

OTHER CONSIDERATIONS – The environment in which a caster will be used must also be considered. Is noise a factor? Dirt, chips, threads or other detrimental substances? Grease, oil, water, steam or chemicals? Temperature extremes? Through various options, lubricants and tread selections, Bond can help you find the caster / wheel combination right for your application.

FOUR SWIVEL - Maneuverable in any direction.  Ideal for confined areas or where equipment must be moved sideways. Difficult to steer in a straight line travel.

TWO SWIVEL TWO RIGID - Easily steered or pushed for straight line travel/ Trails well. Used on a variety of portable equipment.

FOUR RIGID- Diamond pattern, tilt type (usually the center wheels are larger diameter than the ends wheels).  Good for light loads, straight travel. Economical.

TWO SWIVEL TWO RIGID - Diamond pattern, tilt type (usually the center wheels are larger diameter than the ends wheels). Highly maneuverable in tight areas. Turns in own length.

FOUR SWIVEL TWO RIGID - tilt of level type. Highly maneuverable; turns in own length. For heavy loads of long trucks.

THREE SWIVEL - Use where easy motion in any direction is desirable.  Barrel dollies, wharehouse dollies, light machinery.
