Norgren RM/93020/M/20 Pneumatic Cylinder - One-third Length
Part Number: RM/93020/M/20
Quick Summary
RM/93020/M/20 is a compact single-acting pneumatic cylinder that enables precise linear actuation in space-constrained automation lines. In tight machines, bulky actuators increase enclosure size, complicate mounting, and slow cycle times—this model minimizes footprint while preserving stroke and force. Certification details are not listed in the provided data; refer to the datasheet for CE, IP, and SIL-specific ratings. The magnetic piston, corrosion-resistant anodised barrel, and low-friction seals support reliable operation, reduced maintenance, and longer service life in harsh manufacturing environments. As part of the RM/93000/M range, this cylinder offers quick installability, compatibility with standard fittings, and a strong value proposition for compact automation.

Compact form factor delivers space savings and simplifies installation in narrow-spot machines and robot cells. With one-third the length of a comparable ISO/VDMA model, it frees space for manifolds, sensor cables, and other interfaces while preserving a 20 mm bore and 20 mm stroke. The magnetic piston supports reliable position sensing and consistent stroke feedback, minimizing misalignment and improving process control. The anodised aluminium barrel and stainless steel piston rod resist corrosion, extending service life in harsh factory environments and reducing maintenance costs over the life of the line. Operating range from 2 to 10 bar and a theoretical thrust of 119 N ensures reliable actuation for lightweight fixtures and small grippers, enabling higher cycle rates in compact automation tasks. The M5 port and standard mounting interfaces facilitate quick retrofits with existing pneumatic systems, reducing downtime during installation. No cushioning at end-of-stroke simplifies control logic and improves repeatability when combined with suitable stops and sequencing. This design compatibility within the RM/93000/M family supports modular, scalable automation, helping OEMs and integrators standardize actuators across multiple cells and lines.

FAQs
RM/93020/M/20 uses a 20 mm bore with an M5 port, and it provides standard mounting interfaces compatible with common pneumatic manifolds and brackets. The unit’s magnetic piston enables straightforward sensing integration. Consider using compatible mounting blocks and end-caps to ensure precise alignment, while verifying that end-stops are sized to handle the single-acting stroke without cushioning.
The cylinder delivers a theoretical force of 119 N, rated for operating pressures from 2 to 10 bar (29 to 145 psi). This makes it suitable for lightweight actuation tasks such as small grippers or fixtures in compact automation. For reliable performance, ensure the supply pressure remains within spec and account for system losses in fittings and hoses.
Yes. The RM/93020/M/20’s 20 mm bore and 20 mm stroke, combined with its compact length (one-third the basic ISO/VDMA length) and magnetic piston, make it well-suited for compact packaging, assembly, and fixture indexing. The design supports rapid cycling, simple integration with existing piping, and predictable positioning in space-limited cells.
Certification details are not listed in the provided data. To confirm CE, IP ratings, or SIL compatibility, refer to the official datasheet linked in the product downloads. The datasheet consolidates regulatory compliance, material certifications, and installation guidance needed for risk assessment and engineering validation.
The design employs a long-life seal system and a non-corrodible construction with a stainless steel piston rod, reducing wear and maintenance downtime. Magnetic sensing improves control reliability, while the anodised aluminium barrel resists corrosion. Overall, you can expect lower replacement frequency, higher uptime, and a lower total cost of ownership in high-cycle environments.
