Features of GF Plain Bearing

High rigidity, good impact resistance, dust resistance and low cost. Ideal for continuous or intermittent low-speed operation. Not applicable to high-frequency and high-speed cycles (select KF ball bearing for high-speed working conditions).

Compatible Cylinders

DSBC-50, DNC-50, DSBG-50 series standard cylinders. Coaxial installation with a coupling is mandatory.

2. Main Industrial Applications

1) Produzione automobilistica & Component Assembly (Most Typical)

Body welding fixtures, tooling push-pull/lifting mechanisms, long-stroke heavy-duty transfer units, pressing and clamping devices for chassis and door components.

Caratteristiche: Long stroke, large overhanging load, strong lateral force, funzionamento stabile, occasional impact, dusty environment with welding spatter. GF plain bearing delivers higher durability and avoids jamming caused by welding debris.

2) Woodworking & Furniture Machinery

Edge banders, panel saws, sliding table saws, panel loading/unloading and transfer mechanisms, heavy-duty pressing and pushing devices.

IL 450 mm long stroke and high lateral force resistance prevent piston rod sagging, torsion and deviation during panel transportation. The plain bearing is less prone to jamming amid heavy wood dust and features longer service life than ball bearings.

3) Confezione, Logistica & Magazzinaggio

Lifting and transfer of cartons and pallets, end units for palletizing/depalletizing, push-pull devices for heavy bins, diverting and stopping mechanisms on conveyor lines.

Working conditions: Bassa velocità, carico pesante, long-distance transportation, large overhanging load and frequent start-stop impact. GF features excellent impact resistance and requires minimal maintenance.

4) Automazione industriale generale (Macchine utensili, Gomma & Plastics, Stampa)

Machine tool loading/unloading, push-pull of heavy tooling, auxiliary mechanisms for injection molding and extrusion machines, roller transfer units for printing machines, auxiliary guidance for hydraulic and pneumatic presses.

It solves common failures including cylinder jamming, seal damage and shortened service life caused by piston rod sagging, eccentric lateral load and excessive torque under long-stroke operation.

5) Movimentazione dei materiali & Gantry Systems

End-effectors of small gantry machines, vertical/horizontal heavy-duty slides for gantry axes, long-stroke lifting units with vacuum cups or grippers.

IL 450 mm stroke suits medium-span applications. It bears eccentric loads, lateral forces and overturning torques to protect cylinders.

3. Tpical Mechanical Applications & Selection Reasons
4. Long-stroke heavy-duty push-pull/transfer: With a rated dynamic lateral force of 1260 N, the guide unit shares eccentric loads that a single cylinder cannot withstand, preventing piston rod bending and uneven seal wear.
5. Overhanging/eccentric load (Guidance is highly required): Eccentric loads from end grippers or workpieces generate overturning torques (Mx/My/Mz). The GF type provides high torsional rigidity to ensure linear accuracy and avoid torsion.
6. Continuous/intermittent low-speed operation (≤0.5 m/s, ≤10 cycles per minute): Made of wear-resistant bronze with plain friction design, it generates low heat at low speed, offers long service life and strong impact resistance. Replace with KF ball bearing for high-speed operation (>1 m/s and high-frequency cycles).
7. Polveroso, oily and harsh environments: Plain bearing structure resists jamming in wood dust, welding spatter and workshop oil contamination and needs little maintenance, while ball bearings are easily blocked by dust.
8. Linee guida per la selezione: GF vs KF

✅ Recommended for FENG-50-450-GF (Plain Bearing)

Cylinder bore 50 mm and working stroke around 450 mm

Bassa velocità, carico pesante, large lateral force/torque and overhanging eccentric load

Polveroso, spatter-laden or oily harsh environments

Controllo dei costi, low maintenance requirement and impact resistance priority

❌ Not Applicable (Choose FENG-50-450-KF Ball Bearing Instead)

Ad alta velocità (0.5–1 m/s), high-frequency cycles, low friction demand and high positioning accuracy

Clean rooms or dust-free environments requiring low abrasion

5. Application Profile Summary

This guide unit is designed for linear push-pull, transfer and lifting mechanisms with 50 mm bore, 450 mm long stroke, low speed, carico pesante, overhanging eccentric load, large lateral force/torque and harsh dusty conditions. It is a robust guide accessory paired with DSBC/DNC-50 cylinders for reliable protection.

It acts as rigid guidance protection for DSBC/DNC-50 standard cylinders, eliminating problems such as piston rod sagging, torsion, uneven wear and jamming under long-stroke operation.
