Industrial swivel caster with brake «special» 577

Medium duty series «special» 577 – is a series of industrial casters with a contact layer made of elastic rubber.The caster rim is made of nylon.
The casters feature increased wear resistance; effectively absorb vibration; have good shock-absorbing properties; and do not leave braking marks.

Temperature range: from -20°C to +70°C

The swivel caster with brake is equipped with a bracket containing a double-row ball bearing in the swivel head, allowing a change in the direction of movement. It is used to provide trolleys and equipment with maneuverability.
Casters with brakes are used to improve safety when parked on an inclined surface.
Casters made of elastic rubber are most often installed on equipment used in environments with high sanitary requirements: medical stretchers, shopping trolleys, warehouse and transport trolleys in the food service sector.

Information about casters and operating conditions
• Casters are replaceable technical components mounted on equipment, platform carts, and similar devices to provide mobility. This information applies to swivel casters intended exclusively for use on non-motorized transport units and equipment (hereafter referred to as “units”) that are typically stationary and moved at speeds not exceeding 4 km/h.
• Operating conditions primarily include technically correct installation:
– The caster must be securely attached to the unit at all designated mounting points.
– Swivel casters must be installed with their swivel axis in a vertical position.
– Fixed (rigid) casters must be mounted so that their wheel axes lie on parallel lines.
– All swivel casters installed on a unit must be of the same type.
– The load on a single caster is calculated using the formula:
Q = ((M + m) / (n – 1)) × W
Where:
Q – load on one caster
M – weight of the transported load
m – weight of the cart
n – number of casters
W – safety factor (>1 under non-standard operating conditions)
• The caster, bracket, braking and locking systems, as well as the wheel axle, form a single functional assembly.
• A necessary condition for proper caster selection is the availability of data on all potential loads.
