Case Studies
Reducing unplanned downtime in cylinder rod seal
Challenge
During the transfer of fibrous products, a robot arm (equipped with pairs of mini pneumatic cylinders) got fibre dust entrapped through the cylinder rod seal. This caused the equipment to malfunction as well as damage to the packaging. Due to this, there was unplanned downtime.
Root cause: Dusty environment
Objective: Avoid unplanned maintenance and extend machine uptime
 |
Solution
To prevent dust from mixing with the cylinders moving parts, the cylinder body (main rod and guide rod) is revised, and Chesterton Specialists have applied Chesterton 21K Wiper Seal and Chesterton 23K Rod Seal.
Chesterton 21K Wiper Seal
Chesterton 21K Wiper Seal is a positive-rake wiper designed to effectively clean and dislodge foreign matter from retracting rods and rams to prevent scoring and system contamination. The sharp, rugged, flared profile protects against abrasive particles, which can contaminate the system and lead to premature equipment failure. These wipers provide excellent performance for hydraulic and pneumatic
applications.
Chesterton 23K Rod Seal NBR AWC800 is manufactured using a machining process which allows the flexibility to create any size based on equipment dimensions. The radiused-lip design ensures a continuous lubricating film is maintained, which minimizes operating temperature and wear—delivering excellent
sealing performance.
Results
The life of the equipment has been extended by 35 months.
ROI
Before the Chesterton solution:
Labour cost: USD 700 × 6 time = USD 4,200
Packing cost: USD 320 × 2 sets × 6 times = USD 3,840
After the Chesterton solution implementation
Labour cost: USD 700 × 1 time = USD 700
Packing cost: USD 1,165 × 2 sets × 1 time = USD 2,330
Total Savings = USD 5,010 (over 35 months)
