Automated Bearing Washing Systems
This Case History covers two system built for a major bearing manufacturer. Each system had unique characteristics dependent on the process, gross weight, volumes and desired throughput.
The first system (immediately below) processes two baskets of bearings at a time in a three stage aqueous wash/rinse/dry line. The operator stands on a safety mat that locks out the automation during the loading process. The system has a maximum weight capacity of 500 pounds per stage, volumetric capacity of 30"L x 24"W x 18"H per stage and throughput capability of two baskets every 4 - 6 minutes.
The second system (below) processes one basket of bearings at a time in a seven stage proprietary solvent washing line. The operator stands on a safety mat that locks out the automation during the loading process. The system has a maximum weight capacity of 100 pounds per stage, volumetric capacity of 18"L x 18"W x 12"H per stage and throughput capability of one basket every five minutes.
At the heart of each stage of each system is an NFPA Floating Cylinder used to transport and oscillate the process elevator. The process elevator is the basic building block for each step of the process. It is used to produce changing flow patterns that result in dynamic washing, rinsing and drying modes (i.e. platform oscillation combined with solution turbulation, spray and/or high volume air flow). The effect of “dynamic flow combination” is better coverage of component surfaces, more consistent results and accelerated processing time.
Platform roller conveyors are included (see above) to facilitate transfer between stages. The systems are built in accordance with Nema 12 electrical and NEC codes including the control panels, switches, pilot lights and lockout-tagout disconnect switches (see below).
RAMCO Multi Stage Systems are built for the rigors of production. Nothing is placed underneath processing tanks or tucked behind "access" panels. Piping, control valves, pumps, filter housings, pneumatic cylinders, heating elements, etc. are all clearly visible for inspection and accessible for maintenance.
