perma FLEX Single-Point Lubricator, 60 and 125 cm³

A ready-to-use lubricator with a dial for the discharge period

perma FLEX is a compact, fully assembled automatic lubrication system from perma-tec for single lubrication points. You turn the dial on top to the discharge period you want, between 1 and 12 months, and the system starts: an electronically controlled chemical reaction builds the pressure that pushes fresh lubricant to the point continuously.

It is offered with 60 or 125 cm³ of lubricant, works indoors and outdoors from -20 °C to +60 °C, and its IP 68 rating suits very dusty and wet areas. The discharge period can still be changed after activation and the unit can be switched off during long stand-stills.

Technical specifications

Choosing between FLEX and its neighbours

Select FLEX where a simple dial-set unit is enough and the temperature stays within -20 to +60 °C. If you need a boost discharge, choose FLEX PLUS; if the ambient temperature swings widely, NOVA compensates electronically; for precise, temperature-independent metering or longer remote lines, the electromechanical STAR VARIO or ULTRA are the better fit. Work out the cartridge size from the bearing relubrication quantity divided by the interval you want.

Mounting and set-up

Follow the Quick Start Guide: choose the lubricant (the guide uses perma MULTI LC 150-2 (SF01) as an example), the discharge period and the connecting parts, then clean the lubrication point, remove the grease fitting, add sealant, and pre-fill the point and any line with the same grease. For remote mounting the guide shows a support flange (109685), a push-lock hose connector for 9.5 mm inside-diameter hose (116624) and heavy-duty hose (101555). Turn the switch to the period, remove the plug and note the exchange date on the label. Compare with our SKF TLSD SYSTEM 24 single-point lubricator or browse pumps and lubrication equipment.

How the perma FLEX works

The perma FLEX is a sealed lubricator that makes its own pressure. A gas generating unit sits inside the housing. When you turn the dial and activate the unit, an electrochemical reaction starts and releases gas slowly. The gas pushes a piston, and the piston forces grease or oil out through the R1/4 outlet to the lubrication point. The dial sets the discharge period, from 1 to 12 months at +20 degrees C. No battery, pump or electrical supply is needed on site.

Where the perma FLEX is used

• Electric motor bearings
• Pumps and fans
• Conveyor rollers and idlers
• Hard to reach lubrication points
• Dusty or wet areas that suit IP 68

Selection checklist for the perma FLEX

• Lubricant volume: 60 or 125 cm3
• Discharge period of 1 to 12 months
• Grease up to NLGI 2 or oil fill
• Ambient temperature from minus 20 to plus 60 degrees C
• Outlet thread R1/4 and fitting to the point
• Length of any line from the unit to the bearing
• Hazardous area marking, if needed
• Space for the 58 mm diameter body

Installation, commissioning and maintenance notes for the perma FLEX

Screw the unit onto the lubrication point by its R1/4 thread, or onto a short line. Set the dial to the discharge period you want, then activate the system as the instructions say. Write the activation date on the unit. Check that grease is reaching the point and look at the piston position now and then. Replace the whole unit when it is empty. The discharge period can be changed after activation, and the unit can be switched off during a long stand-still.

Requesting a quotation for the perma FLEX

Lubrication records for the perma FLEX

Record the point, the activation date, the discharge period and the replacement date.

Choosing the right perma FLEX model

Choose FLEX PLUS for a boost discharge, NOVA for wide temperature swings, and STAR VARIO or ULTRA for precise metering.

Documents and quotation

The manufacturer flyer for perma FLEX (Art. No. 118456) is attached to this page as a download. For a quotation, send the lubricant you want in the cartridge (grease or oil, brand and grade), the cartridge size, the discharge period, the ambient temperature range, the mounting position and whether the point is in a hazardous area. Please confirm the cartridge type and the approval marking against the manufacturer documentation for your exact order code before ordering; the figures on this page are taken from the flyer and are not a substitute for the operating instructions.
