Linear Shaft Types DLY Can Supply
DLY focuses on precision linear shafts for linear bearings, shaft guide systems and industrial motion applications. Main material options include GCr15 bearing steel and C45 high carbon steel, with regular, chrome plated, soft shaft, supported shaft and custom machined options available according to buyer requirements.
Chrome Plated Linear Shaft
Standard chrome plated linear shafts are commonly used with linear bearings where smooth surface, wear resistance and stable guiding performance are required.
Supported Linear Shaft
Supported linear shafts, including SBR and TBR supported shaft systems, are suitable for longer stroke applications where extra rail support is needed.
Linear Shaft and Bearing Set
Linear shafts can be supplied together with linear bearings, bearing blocks, shaft supports and related components to reduce matching mistakes.
Custom Machined Shaft
DLY supports custom shaft cutting, drilling, tapping, threading, chamfering, step machining and end machining according to buyer drawings.
Stainless Steel Linear Shaft
Stainless steel linear shafts can be confirmed for applications that require better corrosion resistance or special working conditions.
Hollow Linear Shaft
Hollow linear shafts are available for projects that need lower weight, special structure design or customized motion requirements.
How to Choose the Right Linear Shaft
According to bearing size, shaft diameter, material, hardness, surface treatment, length, straightness, load condition and end machining requirement. If the shaft is used with linear bearings, the shaft diameter and surface condition should be confirmed carefully before ordering.
Shaft Diameter
Confirm the diameter according to the matched linear bearing, bearing block or shaft support.
Material
DLY mainly supports GCr15 bearing steel and C45 high carbon steel for regular linear shaft supply.
Surface Treatment
Chrome plated shafts are commonly selected for smoother running and better wear resistance.
Shaft Support
For longer strokes or higher load conditions, SBR and TBR supported shaft systems can be considered.
Length and Straightness
Long shafts need attention to straightness, support method, transport protection and installation condition.
End Machining
If the shaft needs drilling, tapping, threading, chamfering or step machining, drawings should be confirmed before production.
Linear Shaft and Linear Bearing Matching Supply
Linear shafts are usually used together with linear bearings, bearing blocks, shaft supports and supported rails. DLY can help buyers match shaft diameter, bearing model, support type and installation structure to reduce model mismatch.
Linear Bearings
Matched with LM, LME and other linear bearing series according to shaft diameter.
Bearing Blocks
Bearing blocks and open bearing blocks can be selected for shaft guide assemblies.
Shaft Supports
End supports and shaft support blocks can be supplied together for complete shaft systems.
SBR and TBR Systems
Supported shaft systems can be matched with corresponding open bearing blocks for longer travel.
Custom Linear Shaft Machining According to Drawings
DLY supports custom linear shaft processing according to buyer drawings or samples. End machining can help the shaft fit bearing seats, shaft supports, fixing structures or special machine installation requirements.
