The SIJK/SAJK Series maintenance-free rod end bearings incorporate a PTFE composite sliding liner that eliminates the need for periodic greasing. The self-lubricating liner provides consistent low-friction performance throughout the bearing's service life while resisting contamination ingress. These bearings are ideal for applications where regular maintenance access is difficult, including cleanroom automation, food and beverage processing lines, packaging machinery, and outdoor infrastructure joints.
