Motorized precision slides PFS
Motorized precision slides PFS
The FÖHRENBACH precision slides type PFS are engineered for mechanical and special engineering applications, available in five series with widths from 100 mm to 425 mm and strokes up to 2000 mm. They offer a balance of technical performance and cost-effectiveness, featuring minimal installation space, high load capacity, and stiffness. Protection against dirt is provided by bellow covers, with additional cover options available. Materials include anodized aluminum, cast iron GGK-25, and optionally steel C-45. Ball screw spindle drives are offered in T5 and T7 qualities with spindle pitches from 5 to 50 mm. The company has over 35 years of experience in precision slides and positioning systems, ensuring durability in high-stress operations.
The document details technical specifications such as type selection, run-out tolerances, loading capacities, torque loading capacity, and torsional stiffnesses. It also specifies requirements for connecting constructions to achieve desired accuracy and rigidity. Various sizes and configurations are available, each with specific technical specifications.
Model PFS includes a ball screw spindle, screwed bellow covers, integrated inductive limit switches, and components made from anodized aluminum or cast iron. Options include stainless steel lamellas for extra protection and lateral cover sheets for specific mounting types. All slides feature alignment capabilities for parallel component attachment.
The document covers mounting types for coordinate tables, motor selection and mounting options, assembly possibilities, measuring systems, lubrication, controllers, and ordering information. It highlights the importance of leveraging the company's expertise for customer benefit.
Specifications for sliding elements include drill holes for precise attachment adjustments parallel to the guiding direction, using hardened DIN 179A compliant drill bushes.
Detailed dimensions and weights are provided for various positioning units (PFS 100, PFS 155, PFS 225, PFS 325, PFS 425), including measurements for short and long sliding elements and specific weights for aluminum and cast elements.
Two mounting types for coordinate tables are described: MN and MU. MN involves the Y-axis base plate mounted on the X-axis slide, while MU features the Y-axis slide mounted on the X-axis slide.
Various motor attachment types are referenced, with additional details on pages 18-20. Bellows covers with stainless steel lamellas are mentioned for motor drives.
Materials used include cast iron GGK-25 and aluminum, with stiffness and deflection values provided for different mounting types and sizes.
Installation options and dimensions for inductive limit switches are provided, including wiring details to flanged plugs and plug terminal allocation.
Central lubrication systems are available for models PFS 155, PFS 225, PFS 325, and PFS 425, with specific configurations for each model.
Initial greasing and relubrication intervals are specified, with quantities ranging from 0.4 cm³ to 2.2 cm³. Relubrication intervals depend on factors like load, speed, movement, and temperature.
The unipos C110, 420-W, and 820-W/-WH controllers are discussed, each offering different capabilities for automation and CNC manufacturing.
Detailed specifications for profiled guide slides include design, drive type, material, slide size, and surface treatments, allowing for customization.
Orders are subject to the seller's terms, with any conflicting buyer conditions invalid unless agreed upon in writing.
Terms regarding ownership and liability for goods delivered under reservation of ownership are outlined, including insurance requirements and conditions for ownership reservations.
The supplier reserves the right of pre-emption in cases of customer bankruptcy or business closure.
The supplier assumes liability for defects within 12 months from the risk transfer date, offering repair or replacement for parts with significant impairments.
All claims by the supplier become statute-barred after 12 months unless otherwise legally mandated.
The place of delivery and payment is Löffingen-Unadingen, with jurisdiction at the supplier's headquarters. German law applies, excluding the UN Convention on Contracts for the International Sale of Goods.
Founded in 1975, Föhrenbach Group is a leading producer in automation systems and precision machine building, with facilities in Germany, Switzerland, and Ireland.
