Compatible Cylinders

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

2. Main Industrial Applications

1) Producție de automobile & 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.

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

2) Prelucrarea lemnului & Furniture Machinery

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

The 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) Ambalare, Logistică & Depozitare

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: Low speed, sarcină grea, long-distance transportation, large overhanging load and frequent start-stop impact. GF features excellent impact resistance and requires minimal maintenance.

4) Automatizare industrială generală (Mașini-unelte, Cauciuc & Materiale plastice, Imprimare)

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) Manipularea materialelor & 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.

The 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. Prăfuit, 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. Ghid de selecție: GF vs KF

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

Cylinder bore 50 mm and working stroke around 450 mm

Low speed, sarcină grea, large lateral force/torque and overhanging eccentric load
