First, after choosing your caster size and whether it is swivel or rigid and the wheel you would want to decide on a bearing. There are several choices and we have listed the most popular below.
Plain Bore: With this type there is actually no bearing, the axle rides directly on the hub of the wheel. This is often used in extremely heavy duty applications with very high heat or very light duty like displays and furniture.
Roller Bearing: This is the most popular choice, the axle rides on a greased roller supplying an easy and smoother ride, coupled with a axle with a grease zerk, it is easily maintained. Great for indoors and dry environments on dollies, carts and equipment.
Precision Ball Bearings: These bearings are sealed and need no maintenance or lubrication and are great indoors, outdoors, Perfect for most light to medium duty applications. They offer easier, quieter & smoother rolling characteristics than the roller bearing. Some examples; Medical equipment, lab carts, shopping carts, and dollies
Delrin Bearings: Delrin is a thermoplastic that is used a lot with stainless steel and in wet applications because they will not corrode. They roll better than plain bore but not as well as roller or precision bearings. They are also good in food industries, laboratories and bakeries for steam cleaning, there is a high temp delrin also available.
Tapered Bearings: Tapered are used in heavy duty industrial applications due to the nature of the tapered bearing it can handle much more weight. They are also recommended if you are using a tugger to pull your carts or if they are in a tow line, these bearings can handle higher speeds without over heating and failing.
Next options are the brakes to turn your casters into locking casters. Mostly brakes are only used on the swivel caster not the rigid.
Top Lock Brake: This brake attaches to the caster and when the lever is pressed it applies pressure to the top of the wheel.This is our most popular brake for locking casters.
Cam Brake: This style has a larger pedal on the side that when depressed pinches the caster at the bearing and prevents it from moving. This style brake works well but only with roller bearing and plain bore wheels.
Tech Lock Brakes: These are a front pedal brake that also puts pressure on the wheel. This option is easier to operate that the rest but increases your swivel radius.
Total Lock: This brake is similar to the reck lock but also locks the swivel on the casters as well as the wheel. Perfect solution for that cart or table that can have no movement at all.
*All the metal bearings and brakes are also
available in stainless steel for corrosion and rust prevention.
