Welcome to wholesale customized straight end oil catch plate for overhead conveyor chain at competitive price from our factory. Good service and quality products are available.

In an enclosed-track overhead conveyor system, chain lubrication is non-negotiable: it reduces pin-bushing wear, dampens running noise, and extends chain service life beyond 10 000 operating hours. Yet every drop of lubricant that falls from the chain onto a workpiece below carries a direct economic cost - rejected painted parts, rework labour, and production-line stoppages to clean contaminated components. The straight end oil catch plate (also referred to as a chain oil drip tray, oil collection pan, or under-track oil guard) is the single most cost-effective accessory available for eliminating this problem at its source.

The straight end oil catch plate is a formed galvanized steel or stainless steel tray designed to mount directly beneath the straight (linear) sections of QXG enclosed-track overhead conveyor rail. Its U-channel cross-section captures lubricant droplets that naturally shed from the chain as it traverses the straight track, channeling excess oil toward a designated collection point or absorbent pad rather than allowing it to drip onto workpieces, hangers, spray-booth floors, or oven interiors. Unlike generic shop-floor drip pans that sit passively on the ground and occupy valuable operator workspace, the straight end catch plate integrates into the conveyor track structure itself - mounted at track level, out of the operator's path, and sized specifically for the rail profile it protects.

The plate's design philosophy is straightforward: intercept oil drips as close to the source as physically possible. A drip that travels 2–3 metres through the air before striking a workpiece carries enough velocity and spread-pattern width to contaminate a large surface area. A drip that falls 50–80 mm from the chain link into a catch plate directly below the track is contained before it can disperse. This proximity-to-source principle makes the straight end oil catch plate dramatically more effective than floor-level containment alone - and it is the reason painting-line operators and quality managers treat it as essential infrastructure rather than optional accessory.

To understand the value of a properly installed oil catch plate system, consider the chain of consequences that a single oil drip sets in motion on a powder-coating or wet-paint finishing line:

Surface defect formation. A lubricant droplet landing on a workpiece before it enters the spray booth creates a low-surface-energy spot that rejects powder adhesion or causes wet-paint fisheye cratering. The defect may not be visible until after curing, at which point the entire workpiece must be stripped, re-pre-treated, and re-coated.

Booth contamination cascade. Oil droplets falling inside a powder-coating spray booth contaminate the powder-recovery system. Oil-contaminated powder cannot be sieved and recycled; it must be disposed of as hazardous waste. A single shift's oil-drip incident can render 50–100 kg of reclaimed powder unusable.

Oven residue build-up. Chain oil that drips inside a curing oven carbonises at 180–200 °C, forming a hard, insulating deposit on oven walls and air-circulation ducts. This deposit progressively reduces thermal efficiency (increasing energy consumption by 5–10%) and requires periodic oven shutdown for mechanical cleaning - a 1–2 day maintenance window that halts all production.

Slip hazard on access walkways. In lines where the conveyor track passes over operator walkways, oil drips accumulate on the floor, creating a slip hazard that violates workplace safety regulations (OSHA 1910.22, ISO 14122-1). Floor-level absorbent mats are a reactive solution that requires ongoing consumable replacement; a catch plate at track level is a preventive one.

Each of these consequences can be eliminated or drastically reduced by installing straight end oil catch plates beneath every linear track segment where the chain is lubricated and workpieces pass underneath. The plate's unit cost is a fraction of the single-shift cost of rejected parts, wasted powder, or oven cleaning downtime.

The straight end oil catch plate is engineered for long-term, low-maintenance deployment in industrial finishing environments. Its design reflects the practical realities of installation on existing and new-build conveyor lines:

Material & Surface Protection

The U-channel cross-section is the defining geometric feature of the straight end catch plate. The channel width is sized to provide 30–50 mm of lateral capture on each side of the chain centerline - wide enough to catch oil droplets that are shed laterally by centrifugal force at the chain's guide-wheel contact points, but narrow enough to avoid interfering with hanger travel or reducing overhead clearance for tall workpieces. The side walls are typically 25–40 mm high, providing sufficient containment volume for a full shift's lubricant accumulation without overflow.

The catch plate is supplied with pre-punched mounting slots spaced at 400–500 mm intervals along its length, corresponding to standard QXG track support-bracket spacing. M8 or M10 bolts with flat washers and nylon-insert lock nuts secure the plate to the underside of the track mounting brackets or to dedicated catch-plate support arms. The slotted holes provide approximately ±10 mm of lateral adjustment for alignment with the track centerline during installation.

The straight end oil catch plate is offered in model-specific widths and lengths to match each QXG enclosed-track rail profile. The following table covers the standard configurations:

Note: The straight end oil catch plate is supplied as individual 2-metre sections. For continuous coverage along a straight track run, order the number of sections equal to the total straight track length divided by 2 000 mm (round up to the next whole section). A 5–10 mm gap between adjacent sections accommodates thermal expansion without buckling. Custom lengths, non-standard widths, and special drain-port positions are available on request.

The oil catch plate product line is divided into two complementary categories: straight end plates for linear track sections and bend section plates for horizontal and vertical curves. Understanding the difference ensures correct specification for complete conveyor coverage:

For complete conveyor-line protection, straight end catch plates are installed beneath all linear track segments while bend section catch plates cover horizontal and vertical curves. Together, they form a continuous oil-containment envelope that eliminates unprotected drip zones. The straight end plate accounts for approximately 70–85% of the total catch-plate length in a typical conveyor circuit, as straight track dominates the layout of most painting and coating lines.
