A sliding furnace cap features a furnace tube cap and a slider. The furnace tube cap has a bearing assembly arrangement. The slider couples and slides in the bearing assembly arrangement from an inject position to a rinse position, and vice versa, has a cam-like contoured surface with a first ramp configured to couple a first and second raised surface with an intermediate lower surface. The slider also moves and causes the bearing assembly arrangement to force the slider to push against the inner channel sealing arrangement as part of the roller bearing arrangement rides up either the first ramp or the second ramp. The slider also moves and causes the bearing assembly arrangement to allow the slider to float above the inner channel sealing arrangement as the roller bearing assembly rides along the intermediate lower surface when the slider transitions between the inject and rinse positions.
A furnace system has a furnace-tube-cap (FTC) and a slider. The FTC has a first-cap-portion coupled to a furnace tube of a furnace, a second-cap-portion with a bearing-assembly-arrangement (BAA), and an inner-tube-cap-channel (ITCC) passing from the first-to-second cap portion with an ITCC sealing arrangement extending outside the ITCC. The slider slides in the BAA to/from inject-and-rinse positions, and has a first-ramp (FR), a first-raised-surface (FRS), an intermediate-lower-surface (ILS), a second-ramp (SR), and a second-raised-surface (SRS). When the slider moves to the inject-or-rinse positions, the BAA forces a slider-part to push against an inner-channel-sealing-arrangement (ICSA) as the BAA goes from the FR-to-FRS, or the SR-to-SRS. When the slider is in the inject-or-rinse position, a first-slider-part seals the ITCC sealing arrangement. When the slider transitions between the inject-and-rinse positions and the BAA rides along the ILS, the BAA allows the slider-part to float above the ICSA arrangement.
