Our line of maintenance-free casters is designed to reduce the force exerted to turn or start rolling when all caster wheels are not parallel. They feature neoprene-sealed precision ball bearings and hardened raceways, providing smooth swivel rotation with less effort.
These sealed precision ball bearings are pumped with grease and sealed on each side of the ball raceway. The seals lock in grease and prevent dirt or liquid from entering. This attribute extends the caster’s life in the toughest of industrial environments.
Maintenance-free casters do away with the need to grease fittings twice or more each year, but they do not entirely negate the need for inspections and maintenance. Every caster in your facility should be inspected monthly to ensure safety and productivity. Any repairs or replacements should be made immediately to help prevent possible injuries or damage to the loads they support.
Features and benefits of Caster Concepts’ Maintenance Free Casters include:
Maintenance free (no nut that needs to be re-tightened on the kingpinless swivel section)
Keeps dirt, dust, and other debris from getting into the caster
Precision ball bearings roll easier — great for AGVs and continuous-use applications
Overview
When casters are designed to be maintenance-free, they are also designed to last for many years without any changes in their ability to perform. This means that your casters should continue to operate like brand new for years to come, whether they are used every single day or only on occasion.
Maintenance-free casters are often designed to be incredibly ergonomic, as well. They minimize push force which helps to reduce the risk of overexertion injuries.
55 Series | Max Capacity: 1,000 lbs.
57 Series | Max Capacity: 1,500 lbs.
55 and 57 series casters feature completely maintenance-free swivel sections. The smooth swivel action combined with an extended swivel lead helps lower ergonomic forces and minimize employee injuries.
55 Series Caster
57 Series Caster
77 Series | Max Capacity: 3,500 lbs.
87 Series | Max Capacity: 5,000 lbs.
77 and 87 series casters have maintenance-free swivel sections. The 77 caster utilizes a dual (sealed precision)bearing design, enabling smooth and easy rotation. The 87 series caster can support wheels up to 12 inches in diameter.
77 Series Caster
87 Series Caster
97 Series | Max Capacity: 10,000 lbs.
97HD Series | Max Capacity: 20,000 lbs.
97/97HD series casters feature completely maintenance-free swivel sections. As some of our largest heavy-duty casters, they are designed for powered applications, agv’s and situations where the caster is in continuous use. The 97HD caster features a dual row of bearings designed to increase load-capacity.
Maintenance-free casters are found in applications where companies are looking for reducing exertion, maximizing safety, and increasing performance. These casters also excel in continuous-use applications when stoppage and downtime are outside the normal function.

Options
Caster Concepts has a wide variety of caster options. Many of these not only improve function – but also provide safety and add longevity to the product. When considering safety options, the most common consideration would be caster locks, caster brakes, toe guards, and reinforced legs. Options that extend the life of a caster are primarily options that seal the bearing of the caster to prevent contamination of the precision parts.
Other options include threaded zerks for when an application is difficult and high level of maintenance is required and track brush wipers that keep debris from stopping movement or damaging a wheel. These options can be added at the time of manufacturing or after the caster is fully assembled.
Wrap Around Brake
The wrap around brake provides total access to the braking system regardless of the caster orientation.
Single Side Brake
The single-side brake is an economical brake for medium heavy-duty casters with 6- to 12-inch diameter wheels.
Pneumatic Poly Cam Brake
Similar to the standard poly cam brake in operation, the pneumatic poly cam brake offers a greater movement of the brake shoe to compensate for pneumatic tires. The brake is foot-operated.
Face Contact Brake
The face contact brake is activated by tightening the brake shoe against the wheel.
Dual Side Brake
The dual side brake is a cost-effective hub brake. Each brake lever must be engaged by the operator.
Cam Brake
The cam brake is used on lighter-duty casters. This brake provides an efficient, cost-effective hub braking system.
Poly Lock
A polyurethane lock roller engages a steel brake shoe against the tread of the wheel providing positive engagement of the tread. Levers can be mounted “toe out” (shown) or reversed to “toe in.”
Locks
Passive Swivel Lock
The passive swivel lock is used when full mobility of a unit is needed. The swivel lock plunger engages a detent and locks the caster for straight-line movement. When side thrust is applied, the swivel unlocks providing maximum maneuverability of the unit. This swivel lock is NOT RECOMMENDED for towed applications.
Factory Installed Swivel Lock
The swivel lock provides notches every ninety degrees for use in straight line movement of the cart. Also available in 1, 3 or 8 position.
Heavy Duty Swivel Lock
The heavy-duty swivel lock provides a longer, more accessible handle made from machined steel.
Demountable Swivel Lock
The demountable swivel lock is a field-installed option available up to the 71 Series.
Vertical Mounted Swivel Lock
The vertical mounted swivel lock is mounted out of the way, under the yoke base of the caster. Used mostly in heavy-duty applications, this swivel lock provides a more secure locking feature.
Heavy Duty Demountable Swivel Lock
The heavy-duty demountable swivel lock is a field-installed option available for the 80s and 90s series of casters.
Foot Actuated Swivel Lock
The locking mechanism on the foot-operated swivel lock is the same as the standard swivel lock. To engage or disengage the lock, there is a pedal that can be operated by foot to improve ergonomics and speed of locking/unlocking a swivel caster.

Threaded Zerks
Threaded Zerks Grease fittings for every size caster.
Caster Toe Guards
Role of Caster Toe Guards in Workplace Safety
A caster toe guard is a bracket that provides a barrier between the caster wheel and a cart operator's foot. Often used as a safety device, the toe guard is mounted approximately one-half of an inch off the floor. This height can be modified based on the terrain the caster must travel over. It can be used in both manual and power applications.
Track Brush Wiper
Add a track wiper brush for extra protection against debris and build-up. Track wiper brushes are utilized when any type of wheel is running on a track where debris can stop the movement, damage the wheel or take it off the track.
Sealed Wheels
Rubber inserts provide maximum protection against debris within sealed wheels.
Caster Steering Tubes
Slots for steering handles allow precision motion control for casters with steering tubes. Steering tubes are used on industrial casters that carry heavy loads and need to be manipulated in very tight places.
Angle Reinforced Legs
Heavy-duty angle reinforced legs provide maximum strength and rigidity. Reinforced Legs either angle iron on the outside of the leg or gussets on the inside serve to strengthen the caster when exposed to side loading.
Heat Treated Raceways
Heat-treated raceways in swivel casters are designed to prevent brinelling of the raceways.
