Leno System Drive Lever Arm Assembly Blue Painted Double-end Bearing Connecting Rod Heald Frame Spare Part

Product Description:

• This double-end bearing connecting rod is a core transmission linkage component of Leno System Drive Lever Arm Assembly (heald frame leno drive lever assembly). The rod is machined from high-strength aluminum alloy with blue protective coating, and precision rolling bearings are press-fitted at both ends. It realizes smooth rotation through hinge bearings, connects upstream and downstream transmission parts of the lever assembly, steadily transfers reciprocating power and drives the leno mechanism to complete selvedge weaving.
  The aluminum rod balances light weight and structural rigidity, and the blue anti-corrosion coating resists rust, dust and oil contamination in textile workshops. Integrated bearings at two ends eliminate separate bearing selection work, featuring low rotation friction and tiny transmission clearance to avoid jamming and looseness during high-speed reciprocating operation. The small reserved hole on rod body can be used for positioning installation or lubrication filling. The center distance between two bearings and inner diameter strictly follow original assembly parameters, supporting direct replacement of original rod without secondary adjustment on surrounding levers and connecting plates. It adapts to long-time continuous high-speed loom weaving, serving as a frequently replaced consumable transmission part for daily maintenance of leno lever assembly.

Features:

• Lightweight aluminum rod: Low weight with good bending strength, reduce high-speed transmission inertia and mechanism vibration.
  Blue anti-corrosion coating: Resist dust, oil and moisture in workshops to improve rust & wear resistance.
  Pre-installed precision bearings on both ends: Smooth rotation, low friction loss and stable clearance to minimize leno motion error.
  Standard center distance machining: Fully interchangeable with original assembly for easy disassembly & replacement.
  Reserved small process hole: Convenient for installation positioning and regular grease refilling.
  Integral pre-pressed structure: Bearings are firmly fixed with rod, no on-site bearing assembly needed to cut installation workload.

Technical Parameters:

Applications:

• As an intermediate transmission part of heald frame leno drive lever assembly, this rod is applied for leno mechanisms on air-jet and rapier loom heald frames. It transmits power between driving levers, carbon fiber connecting plates and rear leno actuators, and offsets transmission angle deviation via free rotation of double-end bearings to ensure uniform and stable selvedge leno movement.
  When faults including abnormal bearing noise, rotation jamming, rod deformation or rust occur, this rod can be replaced separately without dismantling the whole lever assembly, greatly shortening loom downtime and cutting part cost. It is widely used for regular maintenance of loom leno systems and split spare stock in textile mills, fitting production lines of plain, twill and home textile fabrics needing reinforced selvedge.

Support and Services:

• Assembly compatibility check: Verify consistency of bearing size and center distance with lever assembly parameters to prevent wrong purchase.
  Installation & commissioning guidance: Explain operation points of shaft mounting, circlip locking and lubrication, troubleshoot abnormal noise and jamming after installation.
  1-year official warranty: Free replacement for manufacturing defects such as inherent bearing jamming, rod crack and loose press-fit bearings under normal weaving conditions; bearing burnout caused by collision or insufficient lubrication is excluded.
  Independent split-part supply: Support separate delivery of this rod for customers' individual stocking demand.
  One-stop procurement for full assembly parts: Purchase this rod together with matching levers, carbon fiber plates and other parts in one order.
  Online technical support: Provide advice on bearing maintenance, wear inspection and abnormal transmission noise troubleshooting.

Packing and Shipping:

• The whole rod is wrapped with anti-static bubble film, two bearings are individually covered with foam for dust and collision protection, then put into separate shockproof inner box. Cushion fillers are added in outer carton to prevent bearing displacement and coating scratch during transit. Outer carton is marked with assembly name *Leno System Drive Lever Arm Assembly*, part name and quantity for warehouse sorting.
  Regular orders are shipped within 48 hours. Export orders can be delivered together with other assembly parts with full logistics tracking, neutral unbranded packaging is available.

FAQ:

• Q1: Can I replace only the bearings or need to change the whole rod?
  A: Bearings are pre-pressed integrally at factory. It is recommended to replace the complete rod once bearings get damaged, to guarantee accurate center distance and rotation precision.

  Q2: What daily maintenance is required for the double-end bearings?
  A: Refill high-temperature grease through the small hole on rod regularly to prevent dust ingress leading to jamming and noise.

  Q3: Will worn blue coating affect normal use?
  A: Slight surface coating abrasion does not affect transmission performance. Replacement is recommended if exposed aluminum gets rusted from long-term moisture contact.
