SCHAEFFLER ARCALUB-C4-2P-24V dc Automatic Lubricator Polyethylene Terephthalate

This automatic lubricator supplies controlled amounts of lubricant for industrial machinery in environments with potential explosion hazards. Designed for use in automation, electrical and mechanical settings, it operates across a wide temperature range and can be employed either prefilled or filled on site. The unit is constructed from polyethylene terephthalate and meets recognised hazardous-area regulatory standards for safe use in explosive atmospheres.

• 24V dc drive enables integration with plant control systems
• Adjustable dispensing time allows stepless output regulation
• Refillable up to three times reduces replacement frequency
• IP68/IP54 protection levels permit washdown and immersion
• Operable from −15°C to +60°C supports varied thermal conditions

• Suitable for continuous greasing of conveyor bearings in hazardous zones
• Ideal for lubrication of motor bearings in electrical cabinets with explosion risk
• Used with automated lubrication schedules in mechanical production lines
• Can be used for remote greasing points controlled by plant PLCs

It runs on 24V dc power, permitting direct connection to common industrial control outputs and timers for automated start/stop sequences.

The design supports delivery as a prefilled unit or as an unfilled dispenser that can be refilled on site up to three times to extend service life.

The body material is polyethylene terephthalate and the enclosure meets both IP68 and IP54 protection criteria, allowing operation under dust, splash and temporary immersion conditions.

It holds ATEX-related approval under Directive 2014/34/EU and is also certified to IECEx hazardous-area standards.

The device is rated to function reliably between −15°C and +60°C, so installation should ensure ambient conditions remain within this band.
