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.
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 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.
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.
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.
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.
