Replacement for Stabilus Bloc O Lift

What is Stabilus Bloc-O-Lift?

The Stabilus Bloc-O-Lift is a locking gas spring designed for controlled movement and stable positioning. It is commonly used in adjustable chairs, medical equipment, tables, and industrial applications where precise height or angle adjustment is required. Over time, these components lose pressure or wear out, requiring a compatible replacement that matches original specifications.

Stabilus Bloc O Lift

Key engineering characteristics:

  • Mechanical locking function (internal valve system)
  • High load holding capability
  • Designed for precise positioning applications
  • Sealed, non-serviceable unit
  • Performance degradation occurs due to nitrogen pressure loss or seal wear

Locking Gas Strut Type

Locking Gas Spring is divided into three types, elastic locking gas spring, rigid locking, any mounting orientation rigid locking gas spring and rigid locking gas spring.

Elastic Locking Gas Spring

BLOC-O-LIFT is an elastic locking gas spring, ideal for easy and comfortable adjustment of furniture and panels via a special piston valve system, also allowing these applications to be safely positioned in any position within the range. Provides comfortable cushioning and damping during impact or pulse load peaks, and the best balance during lifting, lowering, opening and closing. Suitable for swivel chairs, massage chairs, etc.

Vertically Mounted Rigid Locking Gas Spring

Rigid locking gas spring vertically mounted, cost-effective rigid locking models are among your choices. If the gas spring is to be locked in the extended direction, install it with the piston rod pointing downwards. If it is necessary to lock the compression direction, install the gas spring with the piston rod facing upwards. Optimal balance during lifting, lowering, opening and closing in any position, suitable for height adjustment of hospital beds, operating tables, as well as armrest and headrest adjustment.

Rigid Locking in Compressed Position

Rigid compression locking gas strut

Rigid locking BLOC-O-LIFT air springs are ideal for applications that require a fixed position even when subjected to high external forces. Compact design, minimal space requirements, and various end fittings allow for efficient installation. Suitable for: head and foot adjustment of hospital beds, operating tables and wheelchairs, height adjustment of walkers, armrests, headrests and driver seats, table height and angle adjustment, etc.

How to Select the Correct Replacement?

To ensure a reliable and precise replacement, it is essential to evaluate key engineering parameters rather than relying on appearance alone. Follow the step-by-step process below to identify the correct equivalent:

Step 1: Identify the Original Part Number

Start by checking the label printed on the original Stabilus Bloc-O-Lift gas spring.
This part number provides the most accurate reference for force, stroke, and configuration. If the label is worn or missing, proceed with manual measurement.

Step 2: Measure Extended Length and Stroke

Measure the extended length (center-to-center) and stroke of the gas spring.

  • Extended length determines installation fit
  • Stroke determines the working travel

Both values must match the original specifications to ensure proper function.

Step 3: Confirm the Force (N Value)

The force rating (measured in Newtons) determines the lifting or holding capacity. You can:Read the value directly from the cylinder (e.g., 400N, 600N) Or estimate based on load weight and mounting geometry. Recommended tolerance: within ±10% of original force.

Step 4: Check End Fittings and Mounting Type

Verify both ends of the gas spring: Ball socket, Eyelet or Bracket connection. Even small differences in fittings can prevent proper installation or cause long-term stress failure.

Step 5: Consider Installation Angle and Application

The effective force of a gas spring changes depending on its mounting angle. For example:

  • Vertical installation → maximum effective force
  • Angled installation → reduced effective force

Always ensure the selected replacement matches the real working conditions.

Step 6: Match with an Equivalent Replacement Model

After confirming all parameters:

  • Force
  • Stroke
  • Extended length
  • End fittings

You can select a compatible replacement model or request a custom solution for exact matching.
